I used DIY3DTech's Leg retainers for the top of the riser. The base and top will raise up your Laser Master 2 about 4 inches higher. I added a foot which can be printed in tpu or some other flexible material and should stop the riser from sliding. I added a bigger foot with holes which can be permanently fixed to your work surface. Without the foot the riser may be a little unstable so be warned to test it before using. I used a rubberized shelf lining underneath and braced it against a vertical surface on two sides and that seems stable enough for me.To get a taller or shorter height you can vary the z height of the base in your slicer. Be advised that the laser will need to be refocused.
