This model can be used, if you only have longer than original length linear rods, or the lengths are not exact.

Remix of the X-Axis with belt tensioner by Boogie

Features

• Both Motor holder and idler holder come in two different variations with different amounts of additional length.
• Additional max length from 6mm to 19mm (use original motor holder for 6mm)
• Fine adjustment for length using m3 screws (can be locked with additional m3 nut)
• Optional holder for Z-Axis Endstop on top or bottom of the motor holder (18mm hole distance)
• Of course the belt tensioner and bearing mounts from the original model still work

Assembly and print settings

Choose the idler and motor end parts depending on how much longer your X-Axis rods are than the original (370mm).

E.g. for 380mm rods use the +6mm Motor end and +7mm idler end to get 383mm available length and some room for the adjustment using the screw.

Refer to the original guide by boogie for assembly instructions and needed hardware: https://www.printables.com/model/56241-x-axis-revision-with-belt-tensioner

I printed it from ABS, but PETG should also work.

Additional Hardware for length adjustment

• 2x M3 Hex nylock nuts
• 2x M3 screws (length based on what fits well, but roughly 10 mm to 20 mm will work

Additional Hardware for optional Z-axis endstop

• 1x M3 Hex nylock nut
• 2x 8mm M3 screws
