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.
Original:
Creality has changed the heatbed undercarriage and also the belttensioner in the meantime. To make the Thing from @mfoltz still usable, I have redesigned the adapter plate. I added also a spacer for the new idler. You have to use two of these and M5x30 bolts to mount the Idler beside the Y-extrusion. You need to drill out the holes in the idler bracket to 5-5.5mm.
Beware: Spacer are for 20mm Y-extrusion only. For Ender pro, you need 40mm spacers and longer bolts (50mm I assume)! You may actually use 4 of the 20mm spacers instead of two. Should work.
A nice endcap to close the 2040 extrusion can be found here:
