I made these for my Bachin Laser Engraver, to raise the engraver up so I am able to engrave on thicker items. The base is thicker with a slightly wider foot, which will fit onto the original feet of the engraver and will raise the engraver up about 2 inches. Adding the other thinner riser between the engraver foot and the base will raise it roughly another 2 inches. Print in sets of 4. You can print additional sets of just the thinner risers if you which to go higher. I have not tested the stability above 4 inches., but the parts should have a snug fit. I did notice a variance in the thickness of the original engraver legs, the same part fit snug on one leg very tight on another and loosely on the other two, putting a layer or two of masking tape or that blue painters tape made the loose ones fit good and snug. I suggest printing this at 100% infill, or at least close to it. I printed one set at 40% and noticed some shrinkage, which made the parts too tight fitting.
