Stanley Fatmax carpet knife replacement parts

My original parts didn't break, but I thought it would be a nice exercise to re-model the two plastic parts: the nut holding the two halves together as well as the “fader” you push the blade out with (I have honestly no idea how to call this part properly)

I love this knife dearly and don't think the parts will break anytime soon, but maybe someone had less luck or just wants a different colour for matching their workshop better.

printing advice

You can print the nut as-is, the thread is coarse so layer height doesn't matter either. No supports needed.

The fader is a bit flimsy, so you need support and I would recommend even a raft (it has lots of slight angles and very little actual contact with the print bed). Because of the slight angles, I'd also print it rather fine, 0.16 or even less. Because it's meant to be bent, a more springy material like PETG is also suggested, less infill and more wall strength will also make it last a lot longer.
