Clip on tool and SD card holder for Prusa MK3/S/S+

I created this because my side cutters were always somewhere else when I needed to trim the end of a filament. Then I added an SD card holder so I'd know where they were too.

The bracket is designed to clip directly to the frame of the Prusa MK3/S/S+ on the right hand side, just above the power supply. It's deliberately quite a tight fit so it gets a good grip. The one in the photo is printed in Prusament PETG but I printed one in PLA and that works too.

Print the model with the top face down and it doesn't need any supports. I printed mine at 0.2mm layer height. The preset in PrusaSlicer will work but you can save a little time (and filament) by setting four layers top and bottom and changing the infill to 15% Grid. My PETG print took a little under three hours.

Fit the bracket to your printer by hooking the square side of the clip on first and then pushing the rounded side over the frame. It should snap into place nicely with a little tension in the clip to make sure it stays where you put it.

If you need to remove this again, just unclip it. I found it easiest to unclip the square side first.
