inflatable costume air fan ring

thingiverse

**Work in progress, kinda**: I remember the only possible TODO in that old project is to optimize it for 3d printing. Like, just add a 45-degree or so angle to the threads. I just don't remember why I didn't make it (because I was new to 3D printing, because it didn't quite work with the original fan, ...?). However, it did work fine. If you ever saw an inflatable T-Rex costume (of many other variants) they are made from the same centrifuge air fan. If somehow you lost the plastic ring that screws those~air fans to the costume I designed it. If on the other hand, you are trying to use a different air system, I also designed the inner ring that fits the outside one. <b>Fusion360</b> There is a settings ToleranceOffset (that must be negative) to help remove some plastic to help with 3d printing. <b>Outer ring</b> There is already a -0.30mm offset applied to encounter for 3d printers
