Clip-on Printrbot brushless blower turbine fan mount - version 2

thingiverse

This revamped object serves its purpose more efficiently than its predecessor. A key improvement is that its arms no longer bend inside the extruder mount; instead, they fit into holes in the mount (with wire passage cutouts) for stability while supporting themselves on the mount's exterior. This design prevents breakage during installation and keeps the object from getting too close to the extruder, avoiding heat-induced softening that could compromise its fan-holding function. The lip that props the fan has been thickened and angled to prevent previous issues of weakness or softening leading to fan melting. Although this design may require support during printing, it is a challenge worth attempting. However, I discovered through personal use that PLA printed versions can droop near the hot extruder, so I replaced it with a tin can section secured by zip ties on the carriage for better durability.
