About this 3D model
Simple and fast linear toggle clamp. Need 3x M4x25-35mm bolts with nuts and 1x M6 nut and bolt in convenient length for the end adjustment. Increase walls for stronger part. I added some glue on the M6 nut on the end of the toggle pin. The push block is just a loose fit, I will probably go for another material for it in the future. I opted for no handles, but these can be glued in place. Approx. 30mm travel
