Glass Tube Holder / Stand (Coffee Bean Cellar)

prusaprinters

I wanted to make a cheaper alternative to what some manufacturers were charging for Coffee Bean Cellars so I bought some flat bottomed glass tubes from AliExpress and designed this stand to hold them.Something like these:https://www.aliexpress.com/item/32813289039.htmlThis stand is designed to fit 30mm width glass tubes but you could always scale it to fit your tubes exactly as you like.I went with 30mm by 120mm (60ml) tall tubes to hold up to 25g of coffee beans but in hindsight, I could have gone with 100mm (50ml) tall ones as I only ever use 18g of coffee beans which never fill the tubes as shown in the pics.There are two versions, one with a bottom and one without depending on your preference.I printed without supports fine but depending on your printer, if you want perfect holes, I recommend printing with tree supports.If you need a funnel for the glass tubes, check out my one here:https://www.printables.com/model/659962-funnel-25mm
