Razor blade handle / bread lame

This is a handle for a razor blade, to be used as a bread lame or craft tool. A clip snugly locks the blade in place while still being easy to replace when it gets dull, and the cover lets you store it safely. 

The various parts may be a pretty snug fit. I recommend wearing them in a little bit without a blade involved so you don't need to use force when you do put in a blade. As always, be very careful with sharp things!

Prints without support. The cover might want a brim for bed adhesion.

A ground-up redesign with heavy inspiration from the original model, with an added cover for safe storage.
