HF Mini Toolbox pen holder Remix with one long lip

Turtles Rule

DMS_Designs pen holder for the Harbor Freight Mini Toolbox remixed to have one long clip/lip instead of two smaller ones, for improved strength and durability.

The toolbox it's attached to has been dropped off the desk it sits on probably 10+ times due to a child, and the pen holder and its improved clip have survived it all. It's also been stained with ink as a pen exploded when the toolbox fell on it during one of the drops.

Looks like crap because I printed it with wet garbage white PLA that I hadn't calibrated for, that I then ran out of during the print, and finished it with silver silk PLA. Ugly but functional, lol.

The pictures are from tonight, March 4th 2026. I printed this on March 14th (I think), 2025. So it's survived a whole year. I'll print another if this one ever breaks.

If you download the step file, you will need to uniformly scale the exported file down to 10% in your slicer. The .3mf is good to go.
