Clips that can mount any 15mm thick fan and snap into the slot in an 8020 extrusion. Can be used with my Arduino board clips to mount a fan over the controller board to keep motor drivers cool. No hardware required!
Printed with ABS, 0.25 mm first layer, 0.2mm remaining layers, no brim, 30% infill, no support material. Print two pieces and you can mount any 15mm thick fan on an 8020 extrusion in any position. Easy modifications include widening the "prongs" to allow mounting thicker fans and thickening the base to stand the fan further from the 8020 rail.
