4th axis in wood

I'm Inspired by the Rotary 4th axis for CNC https://www.thingiverse.com/thing:1877336 I've been milling HDF plates on my router CNC instead of printing the leo69 project, which were removed and had been lying in my workshop. These floor plates are 8.5mm thick. If you decide to machine or laser cut them, use the dxf file and leave recess holes at a depth of 4mm. The dxf file is in millimeters. It's also possible to print the parts in STL format. I made two pulleys from ABS that worked well, but it would be ideal to use aluminum pulleys, especially for the larger one. You can use the original collet design from leo69 or attach a 3-jaw chuck like bobwombles' design at http://www.thingiverse.com/thing:624625, which is what I did. For the pulleys, I used this design: https://www.thingiverse.com/thing:16627 I added STL tail, modified dxf tail, and added side holes to the STL files. Here's the BOM: Head: 1 - Nema17 2 - KFL000 10mm pillowblock bearings 1 - XL 25 tooth 10mm bore timing belt pulley 1 - XL 10 tooth 5mm bore timing belt pulley 1 - 80XL037 80XL 40 tooth timing belt 1 - M10 x 100mm hex bolt 1 - M10 nut 1 - M10 washer 4 - 1/4 x 20mm bolt 4 - 1/4 nuts 4 - M3 x 10 19 - M3 x 12mm socket cap screws 19 - M3 nuts Tail: 2 - KFL000 10mm pillowblock bearings 1 - M10 x 90mm hex bolt 1 - M10 nut 1 - M10 washer 4 - 1/4 x 20mm bolt 4 - 1/4 nuts 6 - M3 x 12mm socket cap screws 6 - M3 nuts
