Bring a used-up Sharpie marker back to life as a handy bit driver.
Two different model files - one for typical ¼" bits, a second for 4mm electronics bits.
Bit is held securely by a 6mm diameter by 3mm thick neodymium magnet printed in place.
A small collar appears between the cap and body to let you know this isn't just an ordinary Sharpie. You can also drill a hole in the cap to make it easy to see the bit at a glance.
Prints well with:
- 0.15mm layers
- Print Settings - Advanced - Seam position: [Random]
- Print Settings - Advanced - Fill gaps: [off]
Insert a pause in your G-code at 22.7mm to insert a 6mm diameter by 3mm thick magnet.
If you need to adjust the fit, I suggest adjusting the extruder flow slightly on your machine.
Hope you find it useful!
