Edit 8/28/25: CHECK OUT THE NEW AND IMPROVED VERSION HERE!

Edit 12/8: Added a “repaired” version of the leg armor, hopefully this fixes issues some have been having.

I kept printing myself more and more armored legs to give them a bulkier look, so I decided to make my own next step and rig up a sci-fi-looking spider walker. I had ideas to bulk up the chest and arms as well, but I left it at just the legs so this could be compatible with whatever other parts you want to use! My primary objective was to make it so everything could be printed with zero supports, since my last model, the blaster arms, could be a bit finicky with supports. All of the models have been uploaded flat face-down, so all you need to do is download them and drop them into your slicer of choice. Everything minus the waist frame and armor need to be printed four times.

I printed every part in PETG and it worked fine for me, I assume it should be fine in PLA, but I can't say for sure.

Note: when attaching the “leg holder” and “midleg” pieces, make sure that the smaller end of the leg and the longer bit of the holder are slotted in, as seen below:

This was my way to keep the joint from moving two ways while keeping a female joint on the leg.

This is my first major Dummy 13 modification with a separate armor and frame, hope you enjoy it!
