Laserpecker LP4 Base Plate

Replacement Base plate insert to allow for multiple jigs without having to reset or reposition every time. You could have a variety pre set, then just drop in and load your design. The holes are 2.8mm diameter which allows for your M3 screws to self tap into them easily.

Or you could use a drill with an M3 Tap in it the thread the holes which is what I do.

You can use them to cut into preventing damage to the original aluminium one.
