How is this better than the stock one?

This belt carriage doesn't use belt clamps which damage and weaken the belts. When under tension the back side of the belt is pressed up against a metal corner which damages it further and leads to it ripping.

This design keeps the belt in place without any fasteners. The only thing you need to install it a belt that is a bit longer than stock.

 

This belt mount is designed for gates gt2 belts that are for the Netpune 4 Plus / Max  Y axis.

Recommended print settings:

  • at least 4 walls
  • ~50% infill

Recommended materials:

  • ABS/ASA
  • PETG
  • NOT PLA

Any low creep material will do, but higher impact resistance and rigidity is recommended.

 

Make sure you tighten the screws all the way or else the carriage can move around

If you want to upgrade your Neptune 4 Plus to have a 9mm belt for the Y axis you can print the carriage for the N4 Max.
