The 27 Spidersaur STL parts organized into just 5 printing plates. You'll need to print plates 2 and 3 twice each, all other plates once. The plates are all sized for printing within a 90x90 build area. The parts are totally centered, so you can feel free to scale it up or down as big or little as you need.

Since a lot of people were saying their copies were very loose and needed glue, I've made the STL plates 18% thicker than the originals. (You can see this in the SCAD file.) My parts slide/snap together VERY well and tightly, with no wiggle. Some of the parts are pretty close to one another, a MK6 stepper extruder or similar is probably necessary.

Thanks to Renosis and Syvwlch for their help organizing plate 5!

You can download all of the STL's or the ZIP of the printing plates. Have fun!


  1. Print all parts, plates 2 and 3 twice.
  2. Assemble.
  3. ???
  4. Profits!

No results.

Thanks for this "thing". Unfortunately, the abdomen assembly is difficult and I am not happy with my results.

No problem! I'll rush you a full refund!

Thanks, man, that's only fair.

But seriously, I wasn't complaining about your spider, I was lamenting my own inability to correctly assemble it. Have a look at the pictures of my spider (well, my version of your spider). You'll see that it looks just fine, except it looks a bit as if it had stomach cramps.

Hi, thanks for this!
But need help for abdomen, I'm going to be crasy!
Sometimes I insert a parts and one other is going out!
Don't you have a plan to make abdomen?

I wish I knew how to put this together :(

Great build plates, many thanks - My one is printed at 2 x sized and in Faberdashery Glow-in-the-dark PLA.

I can't figure out how to get all the parts for the abdomen to fit on the spine. No matter what I try, they get in each other's way. Irritating.

Arrange all of the rib-like pieces, largest to smallest, then put the largest piece on the abdomen, closest to the head. Keep adding the next largest all the way down to the end of the abdomen. It's a snug fit, but totally doable.

Took a pisco sour to get my mind loose enough to get it done, but it's done! I'll post picture tomorrow ;-)

Picture posted. 42 grams of ABS or $2 of printing costs.

Is anyone else having a problem with plate 3? My ToM prints the first couple layers then shifts on the Y axis about 1 mm then continues to print the remainder without issue. I can trim it all down but I was curious if anyone else was seeing the same thing I am.

ToM. HBP. MK6.

I've had the same problem with prints before. I think it may be that you are extruding too much plastic then your print head is dragging through the layers causing enough resistance that the belts/motors skip. I have yet to fully fix this problem with my Prusa, but PLA seems to alleviate the problem to a certain extent. I have bad luck with ABS.

Hey DigitalBytes,

It sounds like you're skipping steps. This can happen if your feedrate is too high, your belts too loose or too tight, motors getting too hot, or if your motors don't have their potentials calibrated properly.

What was your process for converting the dfx files into stl?

Hey Linkreincarnate,

Actually, I just organized the existing STL's from http://www.thingiverse.com/thing:9321http://www.thingiverse.com/thi...

However, you can import and extrude DXF files directly using OpenSCAD:
