Simple Clamp Tool for Tolerance Test

I printed this tolerance test below using a monoprice select mini and got 0.15mm to work with a huge effort, but it would bother me for weeks that I could not get the 0.1mm to move even with all the special hammers and stuff, so I got to thinking of building a special tool to make it easy to push out the moving part and wondered if 0.1mm can pass.

The first one I built broke - so I made it better. It seems it works much better now.

If you have no problem with precarious objects sticking well, don't use any rafts or brims. But if you want to be safe a brim can be used and easily removed .

Of course its a small clamp that can have other uses. If you figured out other uses for it, leave me a note.

Btw, I printed mine at 90% infill. No support, no raft.
