About this 3D model
As requested i design a simple funnel to reduce the mess when charging the silica dryer spool. the funnel fit perfectly the spool so it's easy to put silica inside without spill 2 version, one for the normal spool, one for the large spool printed with no supports in vase mode, just place the larger part on the plate link to the silica dryer spool: https://makerworld.com/en/models/39271#profileId-38305 ENJOY
