I wanted to engrave a larger piece of wood with my laser engraver (JL-1 model). This set of leg extensions allows a longer, or thicker, object to be slid under the frame while allowing the mechanics to move without hitting the object.
I don't know what other engravers may be able to use this style of lift, but you're welcome to see if they fit.
I printed them in PLA with 5% infill and 4layers on the sides, top and bottom.
The slot in the top on the narrower legs is 3.5mm wide and 40mm long and 10mm deep .
The wider leg is 60mm wide and the other dimensions are the same.
I use these with this Z-Axis slider :https://www.printables.com/model/285974-another-z-lift-mechanism-for-79-cenoz-jl1-laser-en
The author marked this model as their own original creation.
