DN110 to 120mm Fan Adaptor

thingiverse

A simple adaptor to attach a 120mm pc case fan to a DN110 PVC pipe. Designed to be used at the thicker end with the rubber seal, the beveled edge provides a dry slip fit. (122mm diameter whereas the seal ID is 120mm) Holes are 1.5mm but serve more like placeholders that can be drilled out to your needs. Please note that my print stopped prematurely due to filament shortage, and as it's not supercritical I left it as it is and will glue it in place to achieve an airtight seal.
