K40 Laser Motorized Z Bed with 8mm Lead Screws

A few modifications to the corner brackets on this thing (https://www.thingiverse.com/thing:3051286) to work with 3/4" x 3/4" aluminum tubing. My tubing measured 15.5mm x 15.5mm inside. The top corners were modified to use t-nuts for 8mm 2.0 pitch lead screws. The sketchup files used to modify the brackets are included. The lead screws were cut to about 105 mm each. I skipped using the tensioner and went with a small zip-tie. I plan to re-mix again to move the motor outside of the table assemble
