Bought a prusa 3 for my younger son that is at college, 3rd yr of mech eng. He is using it for fun, but also to make models/jigs etc for the suspension of their formula sae vehicle. This is done with solidworks.
I can send him solidworks files and he can then slice them etc and print them for me. When he visits (about 90 miles away) he brings the printed models to me.
I wanted an inline switch for powerpole cables. I use powerpole in my 4wd and various things plug in. Many have their own switch, but the pump I use to transfer water from tanks/wells to the bladder in my 4wd doesn't. So, designed up a small box that takes a powerpole pair at each end and runs the +12 through the inline switch. The switch is lit when 'on', so easy to tell what is going on.
Here's a render of the design. Has the slots to key with the powerpoles and also the hole for the roll pin to lock each end in place. Turned out quite functional.
