I wanted a simple to use round bread lame where:

• the razor does not slip or rotate
• the amount of razor sticking out is configurable
• thickness is configurable
• it doesn't require a separate nut and screw

Printing

I use petg, but pla or any other hard plastic would work fine. No raft or support is needed. I like to print this at 100% infill, but 30% works fine. Both the top and the bottom are set at the correct orientation.

After printing and before use, clean up the threads of any stringing. Screw the two pieces of the ufo together moving slowly back-and-forth when you get resistance. This cleans the threads out both on the male and female side. You're done when the two pieces fit tightly together with no gap. Don't tighten too much or the male side may break.

Use

Place a safety razor as shown in the picture. Slowly and carefully screw the two halves together.
