Geeetech Rostock 301 fan - improved
thingiverse
My second version of a cooling fan for the Geeetech Rostock 301. Check my other design for more hints and tips. (https://www.thingiverse.com/thing:2253022) I also made an adaptor to mount a 60mm fan. Not because I had too few cooling, but as a test... I want to go 60mm for the hotend itself, in an attempt to improve temperature break and retraction. See https://www.thingiverse.com/thing:2700454. 22/Dec: added chamfer for bolt heads in upper part
