Open Fan Mount for Rambo V1.3 Board - 70mm

thingiverse

My early-era Rostock Max v1 constantly overheats in the electronics bay below the heated bed during long prints, causing stepper drivers to overheat and skip steps resulting in layer shift and tangled spaghetti. I initially used a 10mm fan from the stock hot end wedged into the space but desired something much larger. P0tluck created an excellent 40mm fan mount for the RAMBo v1.3 board (https://www.thingiverse.com/thing:2740591), so I adapted his design to accommodate a 70mm fan on hand instead. His original design features a No Derivatives license, so I secured explicit permission before posting this and have retained the No Derivatives / Non Commercial license to honor the original design.
