PVA reel case

To resolve the issues i've had with Ultimaker 3 PVA ruining the nozzle I created this.

This is a cover to control a level of moisture to a minimum. there is a bit of friction but I am using this successfully.

there are 2 pockets for silica gel packets to go inside the reel.

I also put this into a poly bag with more silica get packets.

I printed this using my ultimaker 2+

I used 5 x nuts and bolts size : 20 x M3 to put it together.
