Thank you for supporting me!
This is another free 3D model made available for you. I love sharing my models, but designing, testing, polishing, uploading and maintaining them is a lot of work. In case you enjoy this model, please leave a small Donation or Buy me a Coffee. Thank you!
Design
I like being blown on by a fan, so I installed a switch to reverse the airflow on ours. It is the most basic Dometic Fan-Tastic caravanning fan.
What I hadn't considered — the blade profile is optimized for airflow outward and only delivers about 30% in the other direction — just a gentle breeze. So I designed a rotor with a symmetrical profile and printed it with a 3D printer. Now it delivers 90% of the original fan's performance in both directions. :-)
Printing
Designed to be printed using a 0.4mm nozzle and 0.20mm layers and PETG or better. Support from build plate required to support the blades.
