pipette -laser cut +3d print
Its a simpler version of a common pippete concept found here in Thingiverse (like https://www.thingiverse.com/thing:255519 by BadenLab) with a twist, the body is made of a laser cutted material, so is faster and cheaper.
You need:
- 3mm material to cut,
- 1 biro fillings including the spring
- 1 m3x20 bolt and nut
- 1 Baloon
- 3d Printed parts.
