Mini Screwdrivers V3 – Bộ tua vít mini

This is my 3rd (and final) version of my Mini Screwdrivers - perfect for stocking stuffers this Christmas, or to have close by to add all the batteries to the new Christmas toys! I fixed the tolerances in the threads and loosened the fit of the ¼" bit. I also added a space for a ¼ (diameter) x 1/16 (thick) magnet. The magnet can be glued in place. It holds the bit secure and also magnetizes the bit to hold the screw.

SIZE:  50mm tall and 14.5mm diameter.  

FILAMENT:  PETG or PLA

 LAYER HEIGHT:  0.1 or 0.15 (I have not tried 0.2)

INFILL:  15-30% Gyroid

WALLS:  3 or more

If you’re having trouble printing it in PETG, you may need to add a brim or use glue. PLA would probably be strong enough since these are really just for light duty applications.
