[I don't have any fully working code to go with this, i just made the physical parts!]
this hexapod is fully 3D printable without support
you need a 300 x 300 mm printbed to print the larger parts
the mechanical parts are fully done, but im still working on the electronics and code so if you want those stand by!
i based this designed around the TGY-RM-91 Robotic servos and control them with Adafruit 16-Channel Servo Driver
other things you need are 13mm barings, various nuts and bolts
[update 26-09-2019] i added a extra part to make it compatible with most standard servos
i also changed the coxa part 2 to make room for it. if you have already printed it out you can just saw off the little collar on the bottom
[update 08-07-2019] here is a link to my google drive with a prototype code. it is still a work in progress but it has most of the ground work to make it move
[update 30-01-2019] the top part of coxa_part_2.stl was to weak and broke on two of my legs, i updated it with a stronger one.
