API Tube Holder V3 Low Profile Remix

thingiverse

API Master Test Kit is great, but balancing test tubes and keeping organized isn't so easy with what is provided. This stand sits on top of the existing test kit and lid, provides easy to read labeled stands for adding water, testing solution drops, waiting for reactions to take place, and provides a drying rack holding the tubes upside down to drip dry and stay clean. Store and dry your test tube caps as well. Original "Thing" checked most of the boxes: 1. Tubes Holder 2. Caps Holder 3. Tubes Drier I didn't care about a card holder as I generally hold it up to the light anyway, it adds extra height/time/materials to the print, and the extra height gets in the way. Additionally printing the pegs vertically creates an inherent weakness in the structure. By separating the pegs into half you get a nice clean, strong print without the need for supports. A channel on the inside is sized to accept a strip of 1.75mm filament as a guide/core for gluing the halves in place, however I found by pressing the two halves into the square sockets, they hold together without issue. Pull the pegs out and drop them into the test kit box for easy storage.
