40mm Fan Bracket for Jonas Kuehling's RepRap X-carriage

thingiverse

This bracket, designed for a 40mm fan, attaches to Jonas' Reinforced Prusa X Carriage featuring Slim LM8UU Holder (http://www.thingiverse.com/thing:18657). The accessory holder has ends for easy attachment of additional parts. Constructed two weeks ago, this is the first self-designed print on the printer; any mistakes are welcome to be pointed out. Although primarily parametric, accommodating larger fans will cause scaling issues due to size constraints. However, adapting it for other purposes is feasible. The design comprises openscad files within a ZIP archive for convenience. Printed at 30% infill, assembly involves bolting the fan, followed by attaching to the carriage and plugging into the controller. Note that proper fan orientation is crucial; otherwise, it may blow on the nozzle, resulting in 10C temperature drop and "prevented cold extrude" errors. To rectify this, a better ducted version is being developed to direct airflow only towards the part.
