This replaces the bottom idler bracket for KevinAkaSam's Belted Z Mod for an Ender 3 Max. The original bracket is an L shape and made for the Ender 3/3 Pro and other's where the gantry uprights mount on top of the base. The E3Max has the legs mounted to the side of the base. This bracket beefs up the mount a bit and allows for mounting it fully to the uprights.

This is an easy print, no need for supports.

When placing these I used digital calipers, setting one of the idler brackets where I wanted it, I then measured and set my caliper so it wouldn't shift and then placed the other side at the same height from the bottom, then double checked that they were both at the same height before tightening down the belts.

Update: This model has been working great on my Ender 3 Max and I have it now on my ender 3 Pro as the original L bracket on my E3Pro broke on one side. It actually took me awhile to figure out it had broken as the break was slight but enough to turn my prints to crap so I figured I would print this out for it as well and no issues since, doesn't mean there won't be but so far none on either printer. 

Model origin

The author remixed this model.

Differences of the remix compared to the original

This is my own model for the Ender 3 Max, derived from the model for the Ender 3. It's a remix in that I used the dimensions and basic shape from the original model.
