This is not a thing that anyone else is likely to need. I'm putting it up here just as one of the examples of the utility of 3D printing for specialized objects.

This object replaces the spindle knob on our LPKF printed circuit board cutter. The original knob is small and difficult to grip. It's used to tighten the spindle collet holding the milling and drill bits. If it's not tightened fully, the bit can fall out, destroying the board being milled, and very possibly damaging the machine (has happened to the tune of several $K).

This replacement knob just clamps over the existing odd-shaped knob.


Both halves are identical. A couple of M3 screws clamps it together.

The .scad file is included, but this was just intended as a one-off, so don't expect a model of programming.

(yes, it looks like a cupcake, but the shape works...)

Nice work! What model LPKF machine is this for?

It's an LPKF X60, which our group just inherited. There's nothing on the LPKF website about that particular model, though it looks very similar to the current S63, but without the tool changer, camera, who knows what else.

I have an S63, and its a seriously big pile of junk. The new software which teh the xx3 models run is buggy as. The earlier models were ok.. ANd the support from LPKF and their Reseller has been terrible. 10 months, and $30,000 and i dont' ahve a machine that works!!!
