because I print continuously I don't unload the PVA. As a consequence I have an issue with moisture so I designed a casing to minimise the moisture exposure. basically I created two pockets for silica gel packets and a tube. it allows the reel to rotate freely. in addition I put it in a bag along with more silica gel.
so far I haven't heard a pop lol
I printed it on my UM 2+ but I think it will go on a UM 3 but not tried it yet.
