This holds my AFA TOOLING deburring tool in the Modular Tool Rail System. I didn't think the deburring tool holder from it would fit mine well and wanted a special place for it rather than haphazardly tossed in the pencil cup.
I didn't want to deal with supports at the moment so I made the rail mount part separate than the tube holder thing. Just glue them together towards the top like in the photo. I printed in PLA with .2mm layer height.
The holder is a hexagon (6 sided) with 13mm between opposite sides.
DISCLAIMER: I have no idea what I'm doing. Print and Use at own risk.
