This is a remake of a wooden toggle clamp by CNCnuts on youtube. This design is adjusted for 3d printing and uses magnets to stick to the bed. The height of the clamp head is adjustable and i recommend using washers on every joint for free movement.

The joints are connected together with M6 bolts, and the clamp head also consists of a long M6 bolt whose hexhead fixes into the clamp head. It is recomended to use superglue or a nut to secure the hexhead and the clamphead.

The base uses 4 circular neodynium magnets to provide good adhision strength to the laser base.(magnet dimension- 15x3mm). 2xM6x1" bolt [for handle], 2xM6x2" bolt [for Base], 1xM6x(3-4)" bolt [for clamp head].

you can use a TPU/rubber tab at the end of the clamp head as it;ll resultt in better griping of the object. Please adjust the height of the clamphead as required or it may result in the whole clamp coming of the bed.
