OpenSCAD small projects
Aus Hackerspace Ffm
A collection of smaller projects using OpenSCAD:
Fan protective grille
- The Hackerspace main network switch was quiet noisy.
- Original 40 mm internal fan (5 Volt) was replaced by an external 70 mm & 12 Volt model.
- Running at 5 Volts keeps it at a lower noise level.
- To avoid (further) hurts, the fan needed a grille.

Safety first!
Ruler for debugging
- add a simple ruler to OpenSCAD source code
- optical control - prevent getting lost of orientation and size of the result
- ruler will not be part of STL output etc. (using the % background modifier)
