Z Axis Lead screw - Coupler 12 to 8 mm

thingiverse

I had miss printed the pieces; I needed for 8 mm and printed for 12 mm so instead of having 7 more hours of print I made this coupler to use 8 mm steel rod in the 12 mm pcs. So if you have made the same mistake print 4 of theses and put'em where rods inserts into the each side (inner machine side) and you should be fine. Made with Fusion360.
