Rotation Jig for CNC 3018-Pro

thingiverse

I wanted to laser etch a design into a fishing rod handle but didn't want to spend the $ for an expensive rotation jig for CNC machine. I saw a couple of great youtube videos that used the approach of floating the round object over the flat bed on a rod and then using a timing belt to turn the rod as the bed moves. It worked great so here are the parts I designed in Tinkercad to attach to the 3018-pro to make it work. I ordered the timing belt from here: https://www.amazon.com/gp/product/B07JKT5BZQ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
