PolyBox Extender

I really like the PolyBox to keep my filament dry. It really works and also makes the spool roll very easily. This prevents a lot of misprints, especially for larger printing jobs. The low moisture also gives a better surface finish.

I found that the Polymaker PolyBox only holds large spools of PolyMaker itself. I needed some filament from another supplier to fit the box also.

The larger 2,3 kg spools have a bigger outer diameter than the 3Kg spools of PolyMaker. The top of the PolyBox hits the case then.
To overcome this, I created an extension ring to raise the case for about 3 cm. The shape fits the PolyBox exactly, so the seal is as good as without the extension. I also added the tabs to keep the top cover from bending inwards and added some extra to improve the original design.

The part was printed as one piece on a Creality Cr10-5S.

I'm planning on cutting the design in half with an way to connect the parts after printing, to make it possible to print on a smaller m
