Boston Model 18/19 Pencil Sharpener Gear
thingiverse
My girlfriend's pencil sharpener gear broke so I searched for printable models online but found none; instead, I saw someone selling 3D printed replacements for $12.50. This angered me, so I decided to design my own in Tinkercad with a gear script. Printed on Rep2X in black ABS, the center hole may need slight adjustments depending on your printer; it works great after a few test sharpens. You can edit the Tinkercad model and avoid paying $12.50 here: https://tinkercad.com/things/6nqhKOHp530. Print settings: 3 shells, 10% infill, 0.20mm layer height using MakerWare.
