This is designed to fit the back plate of the original Ender3.

This is a remixed, slimmed down version of the MinionD BLTouch mount. It's approximately 33% lighter than the original, weighing in at 4 grams. The reduced size helps minimise interference with after market ducts.

I slimmed this down to minimise the weight on the X axis. You can attach this to the back plate using the original screws.

In the pictures I replaced mine with black M3 bolts for a more consistent aesthetic.

Rafts are optional, I found I needed a small brim (2mm) to help with bed adhesion. No supports required if you print this on the side touching the back plate.

Offsets (x, y): -43.4, -10.2

If you're installing this in an enclosure, I recommend printing this part in ASA / ABS so there's no thermal warping / sag.

The picture shows the part printed in PLA. After running this in an enclosure for some weeks, it began to sag - I reprinted it in ASA.
