Parametric Spool Roller Core (Additional Spool Sizes)

thingiverse

These are the Roller Cores I'm using in my filament dryboxes, so thought I might as well upload them. I'll add more as I add more filament types. I have also slightly modified the 3D models to be easier to print, and simplified a few things. Some things had to do with how the screws fit (and how deep and such). I think I also made the flanges slightly thinner since they don't need to be *that* strong and I needed every millimeter in my drybox (using this in thing 4516699 for anyone that cares). But I can't remember what exactly I changed anymore (been a while now), but I've added the Fusion 360 file, so history should also be included. Links are to (german) amazon, but are not affiliate links and just for reference. *StoreHD PETG 330g* ([link to Amazon.de](https://www.amazon.de/gp/product/B07BTY8L71)) These are rather tiny spools, but come in a nice variety color pack and (used to be) very cheap per kilo price. Made a nice PETG starter pack for me. They are weirdly asymmetric so there's two SpoolGuard sizes for these. Only spool I know that doesn't have equally sized holes on both sides. *Eryone PETG 1kg* ([link to Amazon.de](https://www.amazon.de/gp/product/B07XRK9K7)) I would assume these are the same base spools Eryone uses for other filaments as well. One side of the spool is offset into the actual spool core, but doesn't affect the spool holder geometry (it's a large enough outer hole).
