Clamp M8

I needed a clamp for my DIY workbench. In my bench, I use a aluminium profile 17mm x 10mm from Sauter (https://www.sautershop.de/fraestisch-selber-bauen/aluminium-brprofilschiene/aluminium-profilschiene/).

The clamp needs a M8x100 bolt, a M8 nut and washer.
You can hold down about 50mm on the workbench.

I printed the clamp in black PLA from BQ. Layer height 0,3mm, 50% infill. The base is printed with supports generated by Autodesk MeshMixer.
