DBDO E3D Blower Fan mount

thingiverse

I needed a better Airflow solution, so I came up with this second version, and I'm beginning to like it, so I thought I'd share it. This setup is built for my Kossel Mini, but it should work well with many other printers. My setup might be different from yours... no guarantees! I have it set up on an Azteeg X5 Mini v1.1. The 30mm Hotend Fan is controlled by a temperature switch configured in Smoothie to go on over or off under 50 degrees Celsius and does not respond to M106 or M107 commands. The blowers, on the other hand, are controlled by M106/M107 and use Pin 1.30. I'm grateful to these guys for publishing their models on GrabCAD.

Print Settings: Printer: Kossel Mini - Custom Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 100% Notes: Sliced using Simplify3D You can print the blower mount in two ways: 1) As intended to use, which uses lots of support. 2) Upside down, with a lesser visible surface quality. Post-Printing: 1) Painted with cheap nail polish. 2) Sanded using 120-grit sandpaper. 3) Painted with cheap nail polish. 4) Lightly sanded using 120-grit sandpaper. 5) Sanded using 180-grit sandpaper. 6) Painted with cheap nail polish mixed with suitable thinner (Acetone). 7) Sanded using 180-grit sandpaper. 8) Painted using Airbrush and Createx NeonOrange paint. 9) Spray-painted using Plasticote Clear. 10) Polished the surface with cotton and Silicone spray to lessen "stickyness." This is WAY OVERKILL for this, but I used it to test the process.

The blowers are wired in parallel: BLACK to TIP122 Pin2 RED to +12V TIP122 Pin1 goes to Pin1.30 on the azteeg x5 mini via resistor TIP122 Pin3 12VGND
