Snap-Together Geeetech G2/G2s Layer Fan - Square Fan and Fishtank air tube connector

thingiverse

Snap-Together Geeetech G2/G2s Layer Fan System. However, I didn't have a fan to connect using the parts that they have. I did have a spare 40mm fan I took from the 2nd extruder of the Geeetech g2s (I am only using one extruder). So I adapted it. I think I will ultimately put a better/bigger fan. But for now, this is all I have. I have also considered the idea of feeding the Layer Cooling system with air coming from an external source - such as a very strong aquarium air pump, or similar. I did created a connector that fits an aquarium tube (flex tube goes inside adapter), but I haven't found a strong enough air pump. Suggestions appreciated. You can modify the OpenSCAD source code. If you do, you will need the Fan OpenSCAD library from the remixed Fan/Mount Duct library. Use superglue to get the pieces together. I printed in ABS to make it a bit more durable due to the proximity to the hot end. Print Settings Printer: geeetech g2s Rafts: No Supports: Yes
