Ultra-Smooth Running Spool Holders

ULTRA-SMOOTH RUNNING SPOOL HOLDERS I tried LOTS of spool holders here, but most of them either required screws, bearings or whatever. Most of them were also quite noisy so I came up with a new variant that does not use any unneeded parts and is as quiet as it could be. These simple and easy-to-print spool holders do not require any screws, nor bearings but run WAY smoother than any spool holder with bearings I discovered here. Why is that? Because there is a minimum of friction between each wheel and it's stand. For one spool you need: 4x Wheels 4x Stands 2x Rails All parts are self-explanatory and easy to figure out. It is kept as simple as it could be. Zen style. No screws, no bearings, no fancy stuff. Runs ultra smooth and quiet. All parts are very easy to print, no supports required. For the wheels, use a drop of super glue to fix the seconds spike to the wheel. Tested and works well with spools up to 1kg. Would carry even more.

Works as well as the bigger version but requires less filament and printing time. Use whatever you feel like. You may even try to resize the "compact" version down to 75% as user tthenrie succesfully did (see under "Makes") which still works great.
