== 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.
* OpenSCAD Script [[Datei:Fan-Protector 005.scad|Fan-Protector 005.scad]]
** → render mesh and export in STL format
*** → 3D print on yag-freak's Prusa Mendel - thank you!

== M6 Thumbscrews ==
[[Datei:M6 thumbscrew 002.png|240px|none|thumb|Screenshot]]
* version 007: convert a regular M6 nut into a M6 thumbscrew
* version 008: convert a regular M6 screw (DIN 963, ISO 2009, "Senkkopf") and a nut into a M6 thumbscrew
* useful in [[Zen Toolworks CNC Fräse]] project for simple tool changes
<br>
* Thanx to Byteborg for printing and creation of new screw variations ;-)

== Ruler for debugging ==
[[Datei:Ruler for debugging.png|240px|none|thumb|Screenshot]]
* 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 [http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Modifier_Characters % background modifier])
* Source: [[Datei:Ruler for debugging.scad]]
