Magnetic Snap-on 5015 Radial Part Cooling Fan for Mini Afterburner on Voron 0

prusaprinters

WORK IN PROGRESS - FEEDBACK APPRECIATED!A tweaked version of my original design  to fit the Mini Afterburner.I was a bit disappointed with the cooling performance of my Voron 0 as it seems to be the bottleneck for fast PLA and PETG printing. I thought of a way of mounting a 5015 blower fan similar to the Prusa Mk3s. I also wanted it to be easily removable, as the door will not close with it equipped. I came up with this magnetic snap-on design, which can be added and removed with one hand. The model is designed for the Mini Afternurner and should print without supports. Two 5 mm diameter magnets are required that hold the shroud in place. Any size longer than 5 mm should do the trick.caution:Initially I had all three fans (the two stock 3010 and the additional 5015) hooked up to the same output on an SKR pico board. Somehow this lead to the 5015 fan not working after just a few minutes of printing – and two replacement fans thereafter… I therefore highly recommend to use another plug for the 5015 fan if available. In your printer.cfg you can make use of the multi_pin feature to run current through both of them:[multi_pin part_cooling_fans] pins: gpio18, gpio20 #these are the pins for SKR pico. Put your pins here comma-separated [fan] pin:multi_pin:part_cooling_fans
