I was having an issue where the 3 wheel belt carriage was twisting with a flying extruder. I created this to solve the issue and have more stability. This was on a MicroMake D1 Kossel printer. I used all the factory hardware and added a few more to complete the setup.

Stock belt holder holes in the middle of the carriage are 20mm x 20mm apart in case you want to measure yours and see if it will fit. You can also do 20mm x 30mm or 20mm x 50mm with this option.

You can get the most the parts from Home Depot. Here is what is needs to complete:

Note** The M3 nuts for the tensioner part are really tight to make sure they don't spin. They will need to be pressed in.

3 - M5 x 25 bolt (Can use 30mm long also) (For wheels)

3 - M5 Nut (For Wheels)

Poly wheels from Amazon - https://www.amazon.com/gp/product/B08QTPCGMR/ref=ppx_yo_dt_b_asin_title_o01_s02?ie=UTF8&psc=1

3 - M3 x 12 bolt (For stock belt holder) (Or just use the factory 3 bolts it came with)

6 - M3 x 12 bolt (For the tensioner on the side)

6 - M3 nuts (for the tensioner on the side)
