Heatbed carriage adapter Ender 3 (new Version, not pro) for linear Y-Axis mod

Update as of February 2021!
Added Versions for MGN12H/C and MGN15H/C
Changed OpenSCAD source to make hole pattern configurable.

Update as of November 2020!

I have added two idler-brackets that integrate better with the Ender 3. There is a square one, which resembles the Ender pro optics, and a rounded one. Pick your poison!
You might need shorter M5 bolts and a longer M8 bolt for the Idler. Please check!Other than that, just reuse the rollers from the original idler.
