Simple medium size corner clamp for woodworking etc. Maximum clamping thickness is 30mm. You will be need: 692rs ball bearing (15x6x5 milimeters), threaded rod 130 milimeters long, two M6 nuts, one M6 PTFE nut to secure knob. Only knob need to be printed with supports. I use PLA filament for printing 2 clamps. Before assembling you will be need insert one M6 nut into movement part (square hole) and assemble rod with bearings like its shown on pictures. Happy using :)
