Hi, this is an adjustable laser table for the K40 or any other laser. I bought this one, but it was crap, so I redesigned it. You can also find it on amazon or ebay.
The red parts are printed. The blue parts are a thread rod with 8mm, cut in pieces. The grey parts are original parts. The yellow parts are self-locking nuts in 5 and 8mm, i recommend them. You need 8 bearings 8x22x7mm ( 608 zz) You have to drill 4 holes with 8mm to fit for the rod. I added the drawing of the Original Parts, so you can build it without buying it.
