BG6330 Medium XY Table Anti-backlash Nut

thingiverse

For those with the imported medium-sized BG6330 XY table available at Amazon, I've completely modeled it from scratch and developed a solution to its backlash problems. The entire assembled model including my anti-backlash additions is attached in a STP file for anyone who wants to make further modifications. The anti-backlash creations demanded some innovative packaging to accommodate the spatial limitations under the sliding T-track table. The solution is a direct add-on to the existing brass barrel nuts. To install it, you need to remove the threaded rod first and then place the anti-backlash collar over the barrel nut. Next, reinsert the threaded rod into the barrel nut and continue through the anti-backlash feature. There's a slight preload in the threads that can be adjusted either during the bonding/assembly stage or by applying some heat to relax the 'springs' on the anti-backlash modification.
