We love a good organizationally-motivated print like this one by mogg851 up on 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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
