Tiko Spool Holder

thingiverse

Filament spool holder for a Tiko, designed to fit in Tiko's spool holder cavity and work with standard spool sizes. There are two versions, the smaller version 84mm is pictured. This one was designed to be small enough to be printable on a Tiko, but large enough to work the the spool that comes with the Tiko. The larger version should work with the widest spools that I've seen (here's a list of spool dimensions - http://thrinter.com/empty-spool-weights/). You can also modify the design on Onshape I find that most spool holder in this style work well until the spools are almost empty. When the filament is running out, especially with the lighter spools, the pull of the filament can knock the spool off the bearings. Usually the spool is light enough at that point that nothing bad happens, but it's worth keeping in mind if you use this spool holder. Parts: Assembly requires some M5 screws, M5 washers, bearings, and ball-end hex wrenches. You can use different combinations of bearing sizes to match the filament spools you're using. Use the washers to prevent the bearings from binding on other parts. socket cap M5 screws and washers - the exact length will depend on your configuration but I used 30mm screws. 5x16x5mm bearings - amazon link*, banggood link* 5x14x5mm bearings - amazon link*, banggood link* ball end hex wrenches* - ball-end hex wrenches make it easier to screw in the screws at an angle. glue dots* (optional) - I use a few of these to keep the spool holder in place. Misc: The Tiko spool and an Atomic Filament spool are in the pictures. I find 16mm bearings on the outside for the Tiko spool with 14mm bearings on inside seems good for most of the spools I use regularly, but haven't done much testing. Use small washers between the plastic and bearings to keep them from binding. There are some large printable washers to help align smaller spools, but I haven't needed them yet. When spools are running low, they may not have enough weight to stay on the bearings. This is a work in progress, and has not been tested very thoroughly and may change.
