Here's a hexapod Crab Drone, modeled in openscad. I've been printing it at about 130% on my Ender 3 Pro. I have printed it successfully at 30mm/sec, with both supports and z-hop enabled. I print on blue painter's tape. If you have trouble getting the legs to stick, use a raft.

I was inspired by Scuttler (Mobile Arms) by CosuCreate:

You must print it with supports. After it prints, you can grab the support with pliers and pull it off.

Customizer

You can switch from printing a six-leg hexapod, to a four-leg quadrapod by setting middle_legs to false. You can also adjust the antenna height, and adjust the appearance of the head slightly.
