PVA reel case

thingiverse

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. a 6 mm OD x 4 mm ID tube (old wanhao feed tube in picture)
