PRUSA MK2S Light Bar Bracket

thingiverse

This is a lightweight bracket for mounting various accessories on the PRUSA i3 MK2S. I needed a design that wouldn't obstruct the extruder or spool holder, so I created this snap-fit attachment that secures into the stock hex hole on top Z-axis brackets without any screws or fasteners required. It's incredibly sturdy and won't budge even when pushed down hard at the light mounting points. The bracket has a 2mm clearance above the Z-axis brackets to clear the smooth rod and lead screw. A central screw hole allows for easy attachment of metal clips, securing the LED bar in place. The optimal mounting angle is 30 degrees, which works perfectly with my setup. Since left and right sides are identical, simply print two of these brackets. I used four perimeter walls and 40% infill to minimize flexing, but standard settings of two perimeters and 20% infill might be more than sufficient.
