Bosch Depth Adjustment Knob

Spares support for older Bosch products is patchy at best. Reproducing the depth adjustment knob locally is often quicker and cheaper than the hunt for old stock. With your sample on the bench this is a realistic reproduction job.

Why these break

Adjustment knobs crack at the insert. The original was moulded thin to save cents at production volume. That was fine when the plastic was fresh — twenty years on, there's no margin left in it.

How we reproduce them

The process is simple: drop the part in or send clear photos with a ruler in frame, we confirm fit details, and print replacements — often with a little extra material where the original always cracked.

We print these in PETG-CF. Carbon-fibre PETG is noticeably stiffer than the stock plastic, so the part holds its shape under clamping force instead of slowly creeping loose.

As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
