AT&T BGW320-505 Fan Base

A base to support the AT&T BGW320-500/505 gateway that fits two 40x40mm fans that can be powered by the USB port on the gateway with no issues. The design permits using thicker fans or stacked fan setups, idk but I used 40x40x25mm fans as they were available for $10 and a 2 days wait. Also this design is 275mm at it's longest so without modification may not fit all printers.

I could see this design also supporting other gateways from other ISPs but can't test myself. The idea is easy to adapt to multiple shapes via the PrusaSlicer project file.

Definitely helped as I no longer get any overheating. Just had to add some hot glue “feet” to the fans since I didn't have any actual rubber fan feet like I thought I did but that's all it took to keep the fan blades from riding the infill directly.

Idk it may also be worth noting that my rack w/ several servers, my primary workstation, and two 3D printers all reside in this same 10x11' room.

If you are using PrusaSlicer 2.9.2+ or something compatible just open the project file or add it as a model and adjust the following settings and you should be in business.

Print Settings:

• 0 Vertical Shells/Walls
• 3 Horizontal Shells/Walls
• 5% Gyroid Infill (other patterns may be successful but haven't tried)
• * If using another slicer * Make a 40x40mm modifier for the fan spots to remove horizontal shells so that the fans have an inlet. The prusaslicer project file has the modifiers already in place. If I find a way to make a version of this model that is slicer agnostic I'll upload a v2.
