To enhance the efficiency of the fans in my BentoBox, I aimed to pull more air through the filtration stack and reduce intake from gaps around the 5015 blower exhaust ports.
As a quick solution, I designed a collar to achieve a better seal around the exhaust ports. This collar is intended for printing with TPU so that it can squeeze into place and form a seal. The .step file is also included so that minor adjustments are easy to make for your particular parts.
The author remixed this model.
