This is a fursuit head dryer; you place your sweaty, hot fursuit head on it and it'll dry it out in a jiffy. It accepts a 120x120mm EC fan from Wathai brand on Amazon on the bottom. The holes are designed for M4 bolts, I used 25mm bolts for the feet and 60mm for the assembly (because I purchased the 38mm deep fan). The holes on the feet and corresponding holes on the plate are made to accept 8mm wide by 2mm thick neodymium magnets held in with CA glue.
