12mm Y rod mounting hardware for the Lulzbot Taz 6 printer

thingiverse

I thought the Taz 6 came with 12mm Y rails in stock configuration. It turns out I was wrong. This project aims to create a set that replaces existing stock 10mm rods with 12mm rods. You should consider the Openbuilds V slot Y axis for Taz project on Thingiverse as a better alternative, but this implementation is less expensive. You will need: The stock Taz 6 hardware including the flexi feet 28 M3 heat set inserts 4 M5 heat set inserts The four corner pieces (two left and two right, front to back identical on opposite corners) Four of the retrofit 12mm bed bearing holders Four LM12UU bearings, whatever the one in the Taz 12mm single bearing holder on the carriage is Two 500mm long 12mm rods (preferably hardened) Print Settings Printer Brand: LulzBot Printer: TAZ 5 Rafts: No Supports: No Resolution: 0.50mm nozzle Infill: 85% or better Notes: The bed mounts in particular should probably be ABS or similar thermoplastic. The corners can be other materials. Post-Printing Instructions Print out all of the pieces Insert heat set inserts into all of the pieces. Each bearing mount unit receives four M3 inserts, each corner piece receives one M3 at the top for the rod mount and one M5 for the front plate mount One other insert goes in the foot hole; I'm not sure if it's an M3 or an M5 Remove existing hardware one side at a time, replace with new 12mm hardware The automatic bed leveling should compensate for any change in height. You may lose 1mm with this design total Z travel. A future revision may move that bearing down a bit if it looks to be an issue long term. Happy Printing; let me know if it needs any tweaks!
