Overview

CollarPod is a compact, single-piece flexible bag holder that clips directly onto your dog’s collar so a bag is always there when you need it — even on those walks where you forgot your jacket, your bags, or just your brain. Printed in TPU, it flexes to clip on without any tools and stays put all day.

What It Is & How It Works

1. Flex the back of the pod over the collar edge — TPU flexibility makes installation easy without removing the collar.
2. Fold a standard poop bag tightly — lengthwise four times, then once across. Keep air out for the most compact fold.
3. Close the lid and press until the side tabs click. CollarPod is designed to be firm enough to open that it won’t accidentally pop open on the walk.
4. Check the viewing window before each walk — bag visible means you’re ready to go.

Key Parts & Mechanisms

• Collar clip — flexible TPU grip that flexes onto the collar without tools and holds firm during use
• Lid with side-tab latches — snaps closed securely; firm enough that it won’t pop open accidentally
• Viewing window — confirms a bag is loaded at a glance, no need to open the lid before each walk
• Single-piece design — no assembly, no loose parts, nothing to misplace

Printing Notes & Recommended Settings

• Material: TPU 95A or similar — Bambu TPU for AMS works well
• Nozzle: 0.4 mm
• Layer Height: 0.2 mm
• Walls: 4 (1.6 mm)
• Infill: 40% Cubic
• Support: None required
• Print on a single direct-feed spool for best TPU results

Post-Print Setup

No major post-print work needed. Once off the bed:

1. Open and close the lid a few times to seat the latches — TPU may be slightly stiff fresh off the printer.
2. Flex the collar clip open and snap it onto your dog’s collar. It seats firmly without removing the collar.
3. Load a folded poop bag, close the lid, and you’re done.

Available Sizes

CollarPod is available in three sizes to fit common collar widths, plus a BeltPod variant for humans:

• CollarPod 17 — fits 5/8″ (17 mm) collars → Download on Thangs
• CollarPod 26 — fits 1″ (26 mm) collars → Download on Thangs
• CollarPod 40 — fits 1.5″ (40 mm) collars → Download on Thangs
• BeltPod 40 — clips to your belt (up to 1.5″ wide) → Download on Thangs

Measure your collar or belt before printing. If you’re between sizes, go with the larger variant.

Why This Design Exists

Designed and field-tested in Vancouver, BC — with Bob and Heidi. Because a bag on the dog is always better than a bag you forgot at home.

Overview

A better scraper for 3D printing beds — no screws, no stripped holes, no fuss. The Logical Scraper series solves the two biggest problems with printed scraper handles: stripped fastener holes and multi-piece assembly. Both models use a tool-free design and accept standard 32 mm × 23 mm scraper blades.

What It Is & How It Works

Model A — 2 Piece, Adjustable Angle

The engineer’s scraper. Model A is a two-piece snap-together design with five interchangeable blade holders at angles of 12, 13, 14, 15, and 16 degrees. The handle and blade holder click together using printed hooks and a positive index feature that confirms the holder is fully seated before use.

• 2 pieces — handle + interchangeable blade holder
• 5 blade angle options: 12, 13, 14, 15, 16 degrees
• No screws — snap-together only
• Blade holders swap without tools
• Positive index confirms full seating

Model B — 1 Piece, No Assembly

The minimalist’s answer. One piece. Print it. Install the blade. Done. After designing Model A, I challenged myself to eliminate assembly entirely — no hooks, no indexing, no sliding parts. The blade wedges directly into the handle, and an inspection window lets you confirm full seating before you put it to work. Selectable blade angles are four separate variants: 13, 14, 15, and 16 degrees, with the angle embossed on the handle so you always know which one you’re holding.

• 1 piece — handle and blade holder are a single printed part
• 4 blade angle options: 13, 14, 15, 16 degrees
• No screws — blade installs directly into the printed slot
• Inspection window confirms blade is fully seated
• Angle embossed on handle — always know which variant you’re holding

Key Parts & Mechanisms

• Blade slot — precision-fit channel sized for standard 32 mm × 23 mm scraper blades
• Snap hooks (Model A) — printed hook-and-index system; positive click confirms full seating
• Inspection window (Model B) — confirms blade is fully inserted before use
• Embossed angle label (Model B) — angle is cast into the handle so you never guess which variant you’re holding
• No screws — no stripped holes, ever

Which Angle Should I Print?

I’ve tried them all and find 15 degrees to be the sweet spot for most print removal tasks — but your preference may vary depending on your bed surface and material. Start with 15° and experiment from there.

Printing Notes & Recommended Settings

• Material: PETG recommended; PLA also works
• Nozzle: 0.4 mm
• Layer Height: 0.2 mm
• Walls: 4 (1.6 mm)
• Infill: 40%
• Support: None required
• Print Orientation: As per the included 3MF/STL files

Post-Print Setup — Blade Installation

The scraper blade is extremely sharp and capable of causing serious injury. Handle the blade with pliers only — never bare hands.

For Model A: snap the blade holder into the handle until you feel the index click, then use pliers to press the blade firmly into the holder slot until it seats fully.

For Model B: use pliers to press the blade into the slot from the open end. Check through the inspection window to confirm the blade tip is fully seated before use.

It is a super simple 1-piece print. And, it attaches by simply placing it behind a wall plate. The existing wall plate screws hold the wall plate and the Mini eShelf in place with considerable strength. Definitely adequate enough for small electronics or similar.

A complication I discovered after designing my first one and getting a few followers to test it was, not all wall plates are the same size. So I have created a few size variants to hopefully allow it to work for most people.

On the top back centre of the shelf is a recess (pass through hole) so that electrical wires can be container when using the Mini eShelf for charger or similar activities.

Print Settings

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 and a 0.2mm layer height. For best results, I suggest the following:

Assembly and Installation Notes

No assembly is required. It is ready to go right off the print plate. And, installation is a breeze. Simply unscrew your existing wall plate and then place the Mini eShelf behind it. Screw the original wall plate back into place. That’s it!!

Really not too much else to say about this design. It prints super easily and snaps together. My wife absolutely loves them!

The post Logical Milk Frother first appeared on logicalplanet.

If you know anything about me it is probably that I like lockable containers, puzzles and complex things that are interesting and fun. The BinaryBin pressed all the buttons for me as I started designing it. It is super fun.

The truth though is that I have not used binary and hex for so long I could barely get my mind going but once I did it all came back to me. And, that felt really good.

Click here to download STL (Affiliate Link)

This BinaryBin is about 1 litre in size and features a single-piece base that is secured by the lift of the top. However, the top can only be lifted off when the correct binary code is used by setting the switch values. With a 16 bit code there are 65,536 possible combinations.

I feel one of the most fun aspects of this lockable container is that the 16-bit combination can be saved as a hexadecimal number which means you need to do some conversion and exercise that skill. That adds another layer of “security” to it. So it could be a great teaching (and learning) tool also.

The design uses a planetary gear approach so that the centre gear (the sun gear) is the handle and can be turned if the correct code is selected on the switches. And, when it turns it rotates the ring gear which has the lock latches on it. Therefore, once turned, the lid of the container can be opened and when returned to its original position the lid can be locked again.

I feel the pop-up and lay flat centre hand is a good design that I will likely use again in the future. It makes for a tidy finish when not in use.

Setting the lock combination involves choosing a “0” or “1” switch when assembling the lid. Each of the switches represents one bit of the combination.

I have included TPU bumpers which are entirely optional. I feel they give the container a more rugged look and a bit more finish.
