PenScrewDriver
A pen-sized micro-bit driver with an integrated spudger — designed to be printed at home.
Engineered by PenEngineering. Print it yourself, download the source files, or order one assembled from us. One tool for driving, prying and field repairs.
One Print, Three Tools
A driver, a bit holder and a spudger — fused into a single pen-format body
Ergonomic Body
Pen-format grip tuned for fine, high-torque control. Prints on any FDM machine — no fasteners, no glue, fully self-contained.
Hex Bit Socket
A friction-fit socket holds any standard 4 mm hex micro bit. Press a bit in and it stays seated through every turn.
Integrated Removal Tip
The tail end is a built-in spudger / pry tool for clips, ribbon cables and popping bits back out. One print, two tools.
