C-Clamp

A robust clamp with a swivel foot. This is based off the same idea as my earlier sash clamp design https://www.thingiverse.com/thing:4787182 but is just a one piece body, no wood required. I wanted it for keeping boards aligned during glue-ups and for clamping jigs to boards.
It prints laying down so that the layers are aligned for maximum clamping strength. No supports required. Designed to use a fully threaded bolt and captured nut. Will accept either ½"-13 or M12 bolts. 2 different handle designs are provided, one for carriage bolts - which are often fully threaded, and the other for hex bolts. For this size clamp a 4"/100mm long bolt is ideal. If you can't find a fully threaded bolt in that length, you can do what I did, and glue a nut onto a section of threaded rod.
I printed mine in PETG and it allows ample grip force for wood glue joints.
