About this print
A four-legged walking robot frame optimised for inexpensive 9G micro servo motors and compatible with Arduino-based control electronics. The leg geometry is sized specifically to fit standard 9G servos, and OpenSCAD source files are included for adjusting tolerances to suit different servos or printers. It forms the structural foundation for a small walking robot project. PLA is a practical choice for the frame, providing the rigidity needed for secure servo mounting points.

droger's adaptation of andromeda's quadruped is awesome! I was planning on making my own design months ago. Life got in the way for a while, and BOOM, someone saved me a ton of time! A heartfelt thank you for that :)
Small problem though - the original design didn't fit the cheap 9G micro servos that I had on hand.
So I spent a *smaller amount of time* optimizing the design to fit the servos I (and a lot of other people might) have in stock.
I zipped up the OpenSCAD versions of the parts in case you need to tweak them to fit your servos or printer tolerances.
NOTE: what's shown in the picture are some mid-prototype parts. The finals are actually nicer with rounded corners and whatnot. Fancy!
UPDATE UPDATE: I cleaned up the OpenSCAD files in the zip package. I know some of you have servos with slightly different dimensions. The new scads should be parametric so that you can tweak a few dimensions to get parts that will fit your servos!
UPDATE UPDATE UPDATE: the parametrics now support different servo horn dimensions!
UPDATE UPDATE UPDATE UPDATE: I've included a beta version of the design intended for those that have the Tower Pro version of the blue servo, based on communicated measurements. No guarantees: I do not have one of these servos to test the fit. I do have some on order, but it could be a couple weeks before they arrive. The beta STLs are available in the zipped archive named case_qp_tower_stls-beta.zip .
Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.
Printing Mini Quadruped - optimized for 9G servos
For Mini Quadruped - optimized for 9G servos we would normally reach for PLA — it is the easy, economical default and suits the majority of models. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
