Cheesy Spool, a MasterSpool Remix

thingiverse

12/10/2019 Edited based on NiyaShy's comment. Added a place for the inner filament end to be locked between side 1 and side 2. 02/03/2019 Edited based on @K_Lab and @GanjalfTheGreen feedback. Made it stronger, added an inner filament channel, and made it easier to print. 04/01/2019 I changed the base spool so that it can be used on the "stick" roll holders like the Prusa mk3 uses without a core but still fits 75mm bore, 52.5mm core or a 608 Bearing core. Only side 1 changed, side 2 is still the same as before, cores changed as well. I use the spool without cores because I don't need them on my Prusa i3 mk3. 17/11/2018 I made changes and went to a screw design because the tabs didn't hold up very well. Now it's very rigid and strong and won't get loose while printing. I made two versions of what I call the core, which is slid inside the assembled spool and used to adapt to different spool mounts. The versions here are standard 52.5mm and a version for an 8mm shaft using Skatebearings. The spool can be used without the core when it's rolling on its outer diameter, thus saving even more material. Have fun using this spool! 24/05/2018 The current version uses less than 100g of filament and is still very rigid. It's my third iteration on the Masterspool. I have only designed the 608 ballbearing core yet; will update with 52.5mm bore soon. I made a remix of the masterspool (great idea by RichRap!!) but with using less material without losing too much structural integrity, and being able to use on any printer, be it with a 50mm, 52mm or 8mm shaft with bearings on. I prefer the bearing solution as it unrolls very nicely. Made a cheesy design because I'm from Switzerland. This is Version 0.1 and needs testing before full release; waiting for my refill coils to arrive from Das Filament!
