Fridge Freshener - Gonzo Rocks

thingiverse

This is a box I made to hold Gonzo Rocks so that the dust is contained and I can easily take them out and sun them to recharge without further degrading their structure through handling.Gonzo Rocks are a form of zeolite, a volcanic mineral used to remove odors from the air, which is included in some cat litter mixes. Positively charged ions are naturally attracted to the negatively charged substance. This includes most carbon based particles that create smells.It's 218mm square. That's small enough to fit on many common printers but it's a real test of the limits.Amazon Affiliate Link: Gonzo Rocks
