Silica Gel Containers - Silica Box

Silica gel containers designed with a reduced diameter to be inserted into the central hole of filament spools The taller "v4" version is designed to pass through three stacked spools (my containers hold three stacked spools) and holds approximately 200g of silica The “short” version is sized for a single spool, for example in vacuum storage cases, and holds just over 50g of silica The “nano” version holds approximately 20g of silica and has a 1mm reduced base height The grilles have 1mm openings, sized to retain even the cheapest silica gel, which can have a high variability in diameters, preventing material leakage while ensuring air passage
