Ender 3 Gantry Alignment Tool

I made these brackets to assist with aligning the gantry with the base. You push each bracket onto the gantry ensuring it it pushed on square and being careful not to pinch the belt on the underside.

After printing I suggest you check the two brackets are dimensionally the same so before using.

The bottom of the bracket should sit on the bottom extrusion metalwork (it should fit in between any slot fillers if fitted as per the photos). Each bracket should meet the bottom extrusion at the same time as the gantry is lowered, if not the gantry needs to be re-aligned either by adjusting the rollers/bracketry or the z-rods (if using dual z-rods).

I have added a version for the Ender 3 pro based on the modifications 5als8mgezo made to the Ender3 V2 design, I havent tested it as I havent got a PRO.
