Laser printer Risers

These risers allow you to alter the height of your engraver relative to its bed and also anchors the frame to the bed to prevent movement. initially designed for the Zbaitu M series engraver, it should work with many similar square frame style machines.

Printing:-
I recommend using PETG or better still Carbon Fibre PETG. Print them lying on their backs with no supports and 100% infill for stiffness.

Extras:-
The risers are mounted to the frame using 4 x M5 x 15mm Star Thumbscrews which are available online via Amazon and Ebay. You will also need 4 x M5 slide in T Nuts which are inserted into the frame at the points where you wish to mount the risers. Do not use drop in T nuts as they will fall out each time you slacken the thumbscrews to adjust the height.

You will also need 8 screws to mount the risers to the bed. Its your choice what to use but I used M5 x 20mm screws bolted into captive nuts fitted to the bed. This allows for easy removal for servicing of the bed.
