This is a spool roller with self-centering spool roller for a hermetic food container from IKEA with 10.6L, it should be an exact fit that is split into components to also allow standalone use of one or two spool rollers.

It can aslo be utilized standalone if prefered.

It allows for 2 Spools at a time and do contain a holder for desiccant (it fits 2 bags from the bambulab store at a time) and a location for a very common higrometer.

The only parts that are not 3D printed in the design is the bearings which are the 608zz Roller (22mm outside, 7mm inside) and the Pc4-M10 (the PTFE tube connector), although if you are only interested in the spool roller then you'll just need the bearings.

This design contains 4 main components, the spool roller, the desiccant holder, the spacer and the clips. From which if you don’t need or want to be utilized in the ikea container then the spacer should not be needed since this components work is just to make it tight inside the containers cover.

There is also a Step file in case you are interested in making some modifications to the design. As well as a base for a single roller in case you are just interested in the roller part of the design.

The clips were design to maintain all together in the cover of the food container, making everything stable so the desiccant holder for example does not tip over.

It takes 4 bearings per spool roller, 8 total for the double roller. The bearings are thigh fit by design and they might need some persuasion to get them in (but should not be that tight).
