Ultimate Mini Spool Holder for EIBOS 3D Series X: Easdry

thingiverse

**This is an improved tush-like mini spool holder for [EIBOS 3D Series X: Easdry](https://shop.eibos3d.com/products/eibos-series-x-easdry).** It can also be used on its own as a mini spool holder. It even comes with little stars, what more could you ask for. The EIBOS 3D Series X: Easdry is an excellent filament dryer, however it cannot be used while 3D printing due to the lack of bearings at point of contact with the spool inner hole. The excessive drag will damage your extruder or break your filament. An older tush based spool holder [design from ar300500](https://www.thingiverse.com/thing:5197358) works well, however it takes too much space and thus cannot work with larger spools. This mini spool holder improves on this previous design (fully redesigned in FreeCAD). It has been tested and proven to work very well with spools that just barely fit, such as the [eSun Reusable spool holders](https://esun3dstore.com/collections/reusable-spool). Due to the tight spatial constraints, you may need to slide it in along with the spool in place, do not force it in. To save space, **this design uses F688ZZ bearings**, which are smaller than conventional 608 bearings and have flanges to help hold the spool better. For best results, the bearing flanges should be on the outer part of the spool (as in the picture). Also, when placing the holder into the dryer, the inner holder should be pushed all the way in till it hits the end of the box.
