Test tube holder for 48 25mm/1" test tubes; great for science labs or kitchen spices!
Description
Here's a 24x18cm test tube rack that holds four dozen 25mm/1" diameter test tubes. It takes an obscene amount of filament to print (about 750-850g), but it's a wonderful addition to my kitchen. Perhaps it'd be good for your lab? The test tube volume is a little low so it's not great for spices one uses a lot of. It's great for holding a wide variety of sometimes-used spices in a small space. Suggest using a 0.6mm or 0.8mm nozzle so you don't pull your hair out waiting for it. I used PETG for strength. I suppose PLA could work too, but I've not tried it. I bought the test tubes, corks, and labels separately, but these look like they should do (you'd need 3 sets and will wind up with spares): https://www.amazon.com/WERTYCITY-Pack-75ml-Scientific-Decorations-Cultivated/dp/B08QZDMRFP?dchild=1&keywords=25mm+test+tubes&qid=1615870646&sr=8-13&linkCode=sl1&tag=chrisgagne-20&linkId=3ee414d6fcabfb4233bb835efbe664cc&language=en_US&ref_=as_li_ss_tl
