Worked perfectly, held up even made with regular PLA

Works great, printed with PolyMaker HT-PLA-GF in "power tool red"

Printed perfectly on H2D but it's thick enough that it may not fit in compact drills - double check your drill before printing at full size

Used this to keep critters out of a 1.5" vent stack in our barn. Perfect fit on 1-1/2" schedule 40 PVC

Works great on "Yitahome" brand 12000btu 240v outdoor unit, which is a rebranded "Aux" (brand) mini-split. I suspect this part will work on any Aux rebrand which are very common lower-priced units. Fits perfectly with the hose size that comes with the unit for the indoor condensate pan, too big of a hose barb to fit 1/2" ID tubing (common in USA). Printed with PETG interface layer for supports on H2D with no issues
