More 3D Printing Usefulness
A foot:
There's a screw that fixes the foot to the frame, there's four holes for feet, only two feet. The screw is countersunk so it doesn't damage the surface the foot rest on.
An OpenSCAD model later and we have prototype one:
This was fine, except that I'd left out the countersinking of the screw and the screw hole was too big.
Prototype two has the countersinking.
I printed two of the latest version and so far it looks like they do the job.
