Summary

I discovered recently that a razor blade made a really good tool for cleaning the old glue off my glass 3D printer bed. It also works really well for getting firmly stuck prints off the bed. I went looking for razor blade handles, and while there are a number of them here on thingiverse (and I tried a few). All of them are flimsy, come apart too easily, or require screws or something to mount the blade. In short none of them fit the bill.

This razor handle allows you to simply slide the blade in, and it is tight enough the blade won't be going anywhere. The handle is also strong enough to push down with enough pressure to really get all of the glue off the glass bed. The back of this handle is wide enough that you can put the blade at the base of a print (against the printer bed), and comfortably tap the back of the handle with your hand to pop the print off the bed. This has worked even with my most stubborn prints.

There is now also a version with a hole in the handle so you could hang it.
