I used onshape.com and the dimensions form https://cookierobotics.com/042/ to design a way to mount a motor to a robot. This motor will be used to attach a wheel to a fire fighting robot. I sliced the design with Prusa slicer 2.6.1 and then used a Prusa MINI with generic PLA on .20 mm quality to print two mounts. Below are the finished mounts with a motor mounted.
