This is a pretty big print project because of the size and number of parts required. So give yourself plenty of print time and keep your printed parts organized. The body is made up of a top and bottom section. The bottom (lower) section has two print-in-place snap lock hinges to hold it together with the top section. And, the leg assemblies are all held in place when the two body sections are snapped together.

Conventionally the spider has 8 legs (four on each side) and the front and back legs are longer than the two middle ones. But you can actually build it however you want.

All the leg joints are articulated and have a click mechanism so you can animate the spider however you want.

Printing

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

• Wall Line Count = 2 ( 2 x 0.4mm = 0.8mm walls )
• Top and Bottom Layer Count = 3 ( 5 x 0.2mm = 0.6mm top and bottom )
• Infill = 15%, Cubic
• Ironing = OFF (not needed)
• Support = None required
• Brim = NO (a brim can complicate details of print-in-place parts and parts printed close together)
• MATERIAL: PLA (any material should work fine)
• PRINT ORIENTATION:

Assembly Notes

No assembly or post-print processing is required.

The design is about 240mm across which is a fair-sized print. At that size, it will hold about 150 small candy bars. But you can scale it up or down depending on your printer size and your needs.

I would be cautious to scale it up too much though as the print duration will start to get significant (already about 10 hours on my BambuLab X1). And, I think at 240mm it is already big enough!

The bowl itself has a smooth inside surface which hides a fairly thick wall structure so I suggest printing with 2 lines width walls and about 15% infill is a nice strength-to-weight ratio.

Printing

This pumpkin bowl does not require much functional strength therefore your default slicer settings should work well. I do not recommend using vase mode as that will be too weak.

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

• Wall Line Count (minimum) = 2 ( 2 x 0.4mm = 0.8mm walls )
• Top & Bottom Layer Count (minimum) = 3 ( 3 x 0.2mm = 0.6mm top & bottom )
• Infill = 15%, Cubic
• Ironing = No
• Support = None required
• Brim = NO
• MATERIAL: PLA

This spider is huge – more than 2 feet across (not fully extended). I included a tennis ball-sized dog ball in the above photo for reference. All the joints are articulated with a fine click mechanism so you can move the legs however you want. It is designed for display purposes as opposed to playing with. The main reason I say that is the design is thin and relatively light. To keep the legs spider-like (thin and light) with strong click joints, I ended up with a design that will likely break if you are too rough with it. The click joints are delicate but strong enough to support the spider’s weight and hold its position well.

All the parts snap together (no fasteners required) and can be printed without support.

The main body consists of a top and bottom which are held together by a small snap-on nosepiece and a slide-in tailpiece. Both can be removed but they are tight and hopefully, you do not need to remove them.

The Body-to-leg connectors must be placed onto the body posts before the body is clamped together. The legs themselves can be added afterwards.

The front and back legs on each side are identical; therefore a total of 4 of those. And, the two inside legs on each side are identical; therefore 4 of those. A total of 8 legs are needed consisting of just 2 types.

The 2 sections of the legs closest to the body are snap-together halves and can be separated but I don’t recommend doing it too many times. The snap joints at each end are quite delicate. Also, I strongly recommend holding both sides of the joints before moving them.

My initial design concept was just a large spider, but as I was coming together I thought it would be great if it lit up on the lawn. And, then I remembered I had some solar lamps that I picked up from Costco on clearance a year ago. Those lamps are essentially glass cylinders upon which a solar cap rests. I just lifted off those caps and designed the spider to accommodate it. I added a translucent lens under the spider to let some diffused light out and glow under the spider. I did not want all the light to project out of the spider.

Instead, I wanted some of it to deflect forward. I added a light path running through the spider allowing some of the light to reach the spider’s head where I have made holes for eyes and drop in translucent eyeball. The result is awesome, the eyes glow and the light under the spider makes the spider more visible in the dark.

If you dont have the solar head (as most won’t) you can print a cap to cover the body cavity and if you are creative place your own battery-powered LED inside.

Not necessarily an easy print. Lots of hours and some fine detail are needed. I printed these entirely in PETG. I suspect it could be printed in PLA or ABS. The main body is the longest part of the design measuring about 280mm (11″). So you need a larger print bed for this one. This design will not scale down. Don’t even try. It probably can scale up but I haven’t tried it.

I printed these with a 0.4mm nozzle, 0.2mm layer height, a wall count of 3 (i.e. 1.2mm walls), 2 top and bottom layers. I also reduced my infill to 10%. If your set up bridges well you will have no problem without support. If you are struggling to bridge the two body parts could be printed with support (touching the build plate only).

I originally printed black with red accents (think black widow spider) but I found the black very dark on a dark evening. So I have also printed grey with red accents which I quite like but not sure which is better yet for Halloween night.

Not much time before Halloween this year but if you get started now you will have them done for next. I am still printing a total of 3 of these and will add before photos once they are done. As a result of the time constraints, I have not spent a lot of time optimizing this design.

Oh, one final note, I added a small loophole on the back bottom of the spider so you can attach it to something if you think someone might try to walk off with it. Chances are good in my neighbourhood.

Printing

Material: I choose to use PETG for its durability and flexibility.

My Setup: Nozzle = 0.4mm

My Settings:

• Layer height = 0.2mm
• Line width – 0.45mm
• Wall count = 4 (1.6mm)
• Infill = 40%
• Support = Designed to print without supports.
