Woodrat Things

I'm still working on a template routing attachment for the wwodrat. The latest part I'm trying to make is a clamp for holding work to be morticed. The latest version of the part is here:

the idea is that this is screwed to the template holder plate and the bolts hold the workpiece. This is 3d printed in PLA, and unfortunately it isn't rigid enough, I need to reprint with a different design.
It takes about 2 hours to print this, so I have to pick a window where I can allow this much time to print the part, so it's taking a while to get this done.
