T-Bolts, Nuts, Wingnuts, and Clamps

I needed some clamps to hold down work on the new CNC machine I got.

I have made integrated T-Nut and bolt, so T-bolt. Bolts have standard M8 threads.
I modeled up some nuts to hand tighten, and it was getting rough on my hands, so I added some wings to make wing nuts.
I also added some corner clamps.

When I used the Makerbot 5G I had to up-size the nuts by 5% with PLA. YMMV depending on printer/slicer/material. The clamps in the photos are PETG.
