Bread lame with sheath

This is a bread lame used to score bread before baking it. I made it as a gift my uncle who is a baker. I can’t guarantee that it will work, but at least it looks nice.

It should fit most double edged razor blades. There are two pyramids on the tip that will hold the blade in place and because of the curve on it, the blade will hold everything in place like a spring. There are also two indentations on the knob that will click onto the pyramids for alignment. The tip will flex a bit when installing the blade but that should be fine.

Edited to add a fused pin and knob model called “combined_lock_lame.stl” for anyone who prefers to print these together using more supports. I have not tested this file so it may not work.

Print Settings

Printer Brand: Prusa

Printer: I3 MK3S

Rafts: No

Supports: Yes

Resolution: 0.15

Infill: 20%

Filament: Prusament PLA
Notes:

The only part that needs supports is the knob. All the parts should already be oriented the correct way for printing.

The tolerance between the pin and the hole it goes through is very tight, so you might need to file down the hole a little bit so it works smoothly.

Use some CA glue (superglue) to attach the pin to the knob at a 90º angle and the tip to the handle.
