Rifle clamp / Hog saddle

Print in PETG but I'm sure PLA would be fine. 

Needed:

M8 carriage bolt 80-100mm

M8 nut

Model foam 5mm.

Press the stencil  into the foam to leave a mark that you then cut out. Glue them on the inside with CA glue. I you want to save some filament you can just press the clamp into the foam instead of the stencils. 

Assemble with a M8 carriage full-threaded screw, for me 80mm was enough but 100mm would be better. Dab some ca glue to keep the bolt in place on the top piece.

Put the m8 nut in the knob and glue together the knob pieces. 

I would also recommend to use orcaslicer but the included print profile works.
