Desiccant Container (Insert/Sleeve)

i was using Malolo's Silica Gel / Desiccant Containers but some of the spools where huge or just a bit too large for the spool to move smoothly, so i made these "inserts" to make a better fit for larger/smaller centre holes for filament rolls, Yes they are going to restrict the amount of air exposure to the gel, but the ends are uncovered to allow the moisture to still be absorbed.

nothing special and can be improved 1000x but this is just a "gets the job done" print..

tests are 5mm high so you can check they will actually fit..
