This through-wall venting port has two flap sets so that it is “double insulated” and more resistant to insects and other would-be assailants. I have been using this for a year or so but only now just posting it as I have had several requests recently.

The idea is that on the outside wall, you mount a 4″ duct plate that connects to a 4″ pipe through the wall, and onto which the double-flapped vent mounts.

On the inside, another 4″ duct plate, which connects to the other end of the pipe through the wall, and, on to which you can mount a variety of headers and or an inline fan to assist the exhaust system.

As you have probably seen from my earlier postings, I like having negative pressure in my exhaust system to ensure no leakage and assist the exhaust fans on my various printers. In this case, I have designed it for a low-cost 120x120x25mm inline fan.

The inside headers are designed to work with my quick-connect exhaust and other components so you can build out the system however you choose.

Printing

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

This product was designed for a 0.4mm nozzle, a 0.2mm layer height and the following settings:

• Wall Line Count = 4 ( 4 x 0.4mm = 1.6mm walls )
• Top and Bottom Layer Count = 5 ( 5 x 0.2mm = 1.0mm top and bottom )
• Infill = 40%, Cubic
• Ironing = OFF (not needed)
• Wall Generator: Arachne (If you are using Cura this is automatically enabled by default)
• Detect Thin Walls = Not needed but good to keep ON
• Support = NO, all required support is designed into this product
• Brim = NO
• MATERIAL: ASA or PETG recommended
• PRINT ORIENTATION: As per the STL files

Assembly Notes

Please refer to my video for assembly instructions and other notes.

The post Double Flap Through Wall Vent first appeared on logicalplanet.

Once again the idea is to capture the VOCs from the fan port and from the top of the machine at the same time, and then vent all of that away from the machine when desired.

This new X1 system is essentially a mirror image of the P1S system except that I needed to add a poop container which is part of the natural port on the back of the X1s. The poop container is therefore now part of the exhaust system as it seals off the system and allows the removal of the plastic poops.

And, unlike the earlier X1 system, the exhaust port of this system is built into the back vented corner of the frame and connects downward to the fan port (poop chute) and upward to the exhaust hose connection. The exhaust hose is attached vertically off the back of the Exhaust Port. And, a new manifold (the “Funnel”) connects on the underside of the Exhaust Port to join an Exhaust Vent Cover which attaches magnetically over the X1’s exhaust fan.

This system is also built around the idea of a frame that sits on the top of the X1 (under the glass) and the glass sits back on top of the new frame. The frame raises the glass 20mm. This exhaust is compatible with an AMS.

All the components of this system can be printed on a 250mm bed and all print without print support.

I designed this system to be compatible with my entire exhaust ecosystem which means you need to attach the “TubeEnd” on the top of the Flow-Through Exhaust Port. This requires a bead of glue on the contacting faces. But it is important to note that you can alternatively connect the Variable Flow Valve on the top instead which will allow you to shut the extraction off when it is not needed.

Please note I have now added LED lighting support bars allowing you to install an adhesive-backed LED lighting strip into the top of your machine for additional internal lighting. It is entirely optional.

I have included some small slots for zip ties in case the adhesive on the back of the lighting fails.

The LED strip bars simply drop into the frame and can be added anytime. Adhere an adhesive-backed LED strip to the underside of the LED strip bars and gently bend the strip around the corners. I have included an exit space for the LED electrical cord which can be plugged if not used.

I think you can use most types of LED strips but the 6mm wide style like the one I used is ideal. Here is a link to the one I used (in Canada) and a comparable one in the US.

The post X1 Capture & Vent Exhaust with LEDs first appeared on logicalplanet.

The idea is to capture the VOCs from the fan port and from the top of the machine at the same time, and then vent all of that away from the machine when desired.

This new P1S system is similar to my X1 system but has an extension that reaches down to the fan on the back side of the P1S. This necessitated moving the port in the top-mounted frame to the back right corner.

And, unlike the X1 system, the exhaust port of this system is built into the back vented corner of the frame and is open on the bottom (as well as the top) so that air can flow through the port (as well as out of the machine). The exhaust hose is then attached vertically off the back of the Exhaust Port. And, a new manifold (the “Funnel”) connects on the underside of the Exhaust Port to join an Exhaust Vent Cover which attaches magnetically over the P1S’s exhaust fan.

The post PS1 Exhaust System first appeared on logicalplanet.

When I first started looking for venting and connection systems I was very surprised to find there is not much out there if you want a comprehensive system with a quick connect/disconnect and supporting brackets for mounting the venting lines. So… I developed one.

Introduction

My first design priority and the most difficult challenge was designing a quick connect/disconnect system that a) required only one hand to operate, b) allowed the hose to rotate on the connection to reduce tension in the hose lines, and c) was 100% printable (no hardware required and preferably print-in-place).

My secondary goals included a) making sure the system was reverse compatible with the old-school pipe clamps and b) incorporating a mounting strategy.

My resulting design achieves all of those goals. I am using it to vent 6 Vorons to the outdoors. I added a 120mm fan at the wall side to create negative pressure in the lines and assist the exhaust fans in the Vorons. All together the system works excellently. I am pretty confident it would be equally as effective for other applications including vacuum and dust collection systems.

The Quick Release Head is a single print-in-place part. I needed to design into it special support that allows the overhanging “teeth” to be printed parallel to the print surface.

All the other components of the system, I refer to as the accessories, are assembled from multiple sections and glued together. This allows very clean and crisp mating areas and consequently a very solid and fast connection between the parts.

So far I have created the following accessories:

• Straight Connector
• Y-Connector
• 6060 Fan Connector
• 120×120 Fan Connector
• 120×120 Fan-Wall Adapter
• Head Cap and Tube Cap
• 100mm and 200mm Extensions, and
• various mounting solutions (listed separately below).

I have not developed a blast door yet but if anyone wants it I can develop one. If there are any other specific add-ons you would like let me know and I will do my best to develop them.

How it Works

The connection between the Head and any accessory is made by teeth on the flex handles of the Head extending into the groove on the accessory. And, this is only secure because both parts have surfaces parallel to each other. With one hand you squeeze the handles and the teeth pull away from the centre of the accessory allowing it to be withdrawn. Letting go of the handles allows the teeth to return.

The cross-sectional view tries to illustrate this essential design component which then dictates how the parts are printed.

The Head requires some built-in support to create a precision lower edge that is overhanging and parallel to the print surface. I have included support that seems to work quite reliably and creates a relatively sharp edge that locks the accessory in (so do not add support when slicing this).

To achieve similarly sharp edges in the accessories they are printed in sections that must be glued together after printing. As the mating surfaces are designed to be very close gluing is very easy and effective.

Building the Accessories

Each of the Accessory Parts has a core component that defines its purpose and then you add to it one or more end rings. The diagram below describes it better than I can write it. In addition, a mounting ring is optional (but recommended) for the Y Connector. The mounting ring allows the Y Connector to be snapped into a wall mount. The Straight Connector has the mounting ridge included.

In addition to the components described above, extensions are also optional for all of the components. The extensions are 100mm and 200mm in length and can be stacked to whatever length you want. Using extensions can minimize the amount of flexible exhaust lines you need and also can be used to join accessories to create a manifold if desired.

The following is an example of how the extensions can be used to create a manifold. The benefit of this in my case is more structure to eliminate some of the movement in the entire system.

The Mounting System

I added an external ridge around the mountable components and then a snap-on mounting bracket that indexes on that ridge. I have made a wall mounting plate as well as a series of mounting brackets to go onto the heavy shelving I am using.

The wall mounting brackets, shown above, clamp onto the Accessory Parts using the ridge on the accessory to index with the groove in the wall mount clamp. The opening portion of the clamping bracket is print-in-place and no support is required.

I have also developed a mounting system for shelves which I will include in another posting about shelf accessories.

Wall Vent

In my situation, I wanted to vent to the outdoors and to do that I created a dual port manifold that sits onto a 120mm variable speed fan (connected to a smart/wifi switch). The fan pulls air out of the exhaust lines creating a slight negative pressure so that no smells escape the exhaust system even when no printer’s enclusure fan is running. The fan then connects to the wall via the Wall Vent Port which, in turn, connects to a 4″ duct exiting the wall to the outdoors. I just used a dryer-style vent cover on the outside.

Construction

I have created a numbering system which is used in the various diagrams in this posting to help identify the print parts for each accessory. Use those numbers to select the parts you need to print.

You will need to glue the accessory parts together after they are printed. And, depending on the material you print with you may need to find an effective adhesive. In my case, using PETG, the B7000 adhesive sourced from Amazon works really well. Apply a small bead of adhesive around the part as illustrated in the image above and give it a half turn. Then let it cure, in my case, overnight.
