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
