Silica box for filamet spool, fits most brands

This is a box for silica gel. mThe box will fit differnt types of filament spools. Fill it only like 80%, so the silca can move free within the box. This helps to maximize the drying effect. If printed from ABS or ASA the silica can stay in the box while refreshing.

The additional weight helps if the spool gets emty to avoid problems with AMS. Non Bambulab-spools tend to tilt. This can be resolved by additional weight.
