quick grip clamp

Quick release Bar clamp.Great for holding glued parts. It relys on a plastic beam that is strong for plastic. But not as strong as a metal bar clamp. So you can apply excessive force with itother simple printed clamps are excesivly weak. and steps don't allow fine tuning. Some assy required. Fine adjustment for clamp. Depending on the specific head for the large screw will define what knob you want. There are lots of printed knobs available. I happened to have a ¼-20 hex head handy. The beam has several sizes in the file. Fits diagonally on build plate. The bed sizes there are files are for are 180, 250, and 325. The other sizes are in the cad files. Maker world is not allowing the parts to hang off the build plate. The beam in the main 3mf file is for the x1c. To add some metal to strengthen there is a penny as the latch. Press the penny in the slot. there is a viewing hole to make sure it is in all the way. assembly instructions:lots of simple stepsremove support.insert penny, us
