Hydroponic base for 3 glass test tube (Base ou support hydroponique 3 tubes à essais)

thingiverse

Hi there, This is a really simple and cute base to support three glass test tubes that are 15x150mm in size. The design is light and discreet, making it perfect for highlighting the growth of lentil sprouts. It's a fun and simple project that children will love. You can place it on your desk at home or in the office. To get started, simply push a small piece of cotton into the bottom of each tube, add 2ml of water, and drop in five or six lentils. After two to three days, they'll start growing! Just remember to add 1ml of water every two to three days. You can find the test tubes you need at this link: <a href="https://www.aliexpress.com/item/Kicute-10pcs-pack-Lab-Glass-Test-Tube-With-Cork-Stoppers-15x150mm-Laboratory-School-Educational-Supplies/32800266601.html?spm=2114.search0104.3.2.459f5501TZgKPH&ws_ab_test=searchweb0_0,searchweb201602_2_10065_10068_319_10892_317_10696_10084_453_10083_454_10618_10304_10307_10820_10821_537_10302_536_10902_10843_10059_10884_10887_321_322_10103,searchweb201603_6,ppcSwitch_0&algo_expid=e4342fab-2725-473b-b86c-e823aadfdf1a-0&algo_pvid=e4342fab-2725-473b-b86c-e823aadfdf1a&transAbTest=ae803_3">15x150mm Test Tubes (Pack of 10)</a> at a great price.
