Artillery Sidewinder X3 Plus Y axis linear rod conversion mod

Y-axis linear rod conversion for the Artillery Sidewinder X3 Plus using 10 mm rods and LM10UU bearings.

My printer came from the factory with the bed's V-rollers aluminum extrusions slightly out of parallel, making proper adjustment of the V-rollers impossible. I made this to circumvent that issue. Hopefully this helps anyone dealing with the same issue.

The mod uses:

2× 500mm long 10mm rods (i used hardened steel HRC 60)
4× LM10UU linear bearings
4× M5×10 mm socket head screws (10 mm is the minimum length) for the front and rear mounts.
6× short M4 (or smaller diameter) bolts with nylon lock nuts or threadlocker.
2× M3 heat-set inserts and M3 socket head screws to secure the rods at the rear.

Requires tapping the rear ends of the 2020 extrusions with an M5 tap. The rods are a press fit in the front mounts. The LM10UU bearings are also press fit—I used a clamp to press them into place.

This is still an early version, although I've been running an even earlier prototype on my own printer for over 40 hours of printing without any issues.

I printed the parts in PETG-GF with 5 perimeters and 50-75% infill. They've handled over 40 hours of regular PLA and PETG printing, as well as over 24 hours of filament drying at 75°C, without any noticeable warping or failures. X3RodsBedV4 requires supports on the lm10uu housings, and X3RodsBackSides probably requires a brim.

The design is not final yet. Planned improvements include redesigning the belt mount so it aligns better with the front pulley and making the bearing holders shorter and closer together to reduce the need for supports during printing and improve access to the mounting bolts, but it already fixed my problem so unless someone asks for it this is it. I included the .f3d files if you want them.
