Fully 3D printable Cam F Clamp

Unlike screw and quick-grip clamps, these don't have enough travel and power to force far objects to be closer. But it is good for quickly holding things together and delivers enough force to crush your fingers if you try hard enough. I made a few different sizes to accommodate different printers. 

Settings I used to print this:

nozzle diameter: 0.4mm

top/bottom thickness: 1mm

line width: 0.4mm

layer height: 0.2mm

perimeter: 1.2mm

infill: 20% 

build plate adhesion: You might need a brim or mouse ears for the lever of the jaw. Glue stick on the build plate is good enough adhesion for me.

wall order: inside → outside 

filament: PLA+

supports: Only in the rectangular hole, I use support blockers over the cam's cavity and the lever and hope my bridging settings are good enough.

Troubleshooting: I find that the clamp will slip if the fit is too tight. The jaw needs a tiny bit of wiggle to catch.

You can sand the contact areas of the jaw so they have more grip.

Design features:

1. fillet on the jaw corners to help ensure the clamping surface is flat, just in case your linear advance isn't tuned.
2. The clamp can stand with its jaws up. Useful if you need to clamp under something or just use the clamp to prop something up.
3. The cam lever closes inward, that way the arm is not in the way when in use. It does make the jaw longer and harder to print on smaller machines. (you might have to print it diagonally)
4. The cam action and jaw move quickly, great for things that need a quick temporary clamp. Like clamping a piece of wood to the drill press for a quick hole.
5. The rectangular hole is 1.5inch x 0.75inch. So my American audience can get a 1x2 piece of wood and make their own super-long clamps. The strength may not be as good but it can be good for holding two boards still for some screws or glue.
