Open upcycle fan

** "Open upcycle fan" **


These are 3D printing parts to upcycle 120 / 140mm fans and generate a standing fan or a matrix of fans.


design goals:
* fast assembly DIY fan from standard electronic parts like old PC power supplies for heatwave relief.
* optimized for FDM
* modular design for connecting a matrix of fans f.e. 1x1, 1x2, 2x2 and so on.
* sturdy but material saving(less printing time/ energy efficent) connectors
* optional handle


additional parts needed:
+ 5mm fan screws or 4mm screws and nuts
+ base plate f.e. wood
+ fan grill(s)
+ optional: some kind of fan control like Noctua NA-FC1(PWM) / adjustable power supply / potentiometer

notes:
* how many fans you can connect is limited by the sturdiness of used fans and filament material.
* the electrical parts like power supply, cables and so on should be safe to use and need
