Ultimate Laboratory Stand

A stand for small objects in your laboratory. I designed it for test tubes, but it can be used for almost anything small and cylindrical. If you have more than one, you can easily link them together for a tidier bench. You will need some springs. I used 4mm*10mm ones (link after the instructions). I don't personally work in a lab, but I have used them in my chemistry classes and for things in my workshop. I hope you find it as useful as I did!

Building instructions

Step 1: Print

Print out all the necessary parts in the correct quantity.

Step 2: Preparing the grippers

Take one of the clamps and one of the springs and assemble them as shown in the photo. If you are planning to use larger test tubes, you may want to put some tape on the front of the gripper to give it a better grip.
 

Step 3: Mount the Gripper

Take the Gripper and fit it through the top hole in the front cover.

Step 4: Assembly Bracket

Take the bracket and slide it onto the gripper. I recommend using a little glue for extra stability.  Make sure the spring stays in place. There's a small hole in the bracket to hold the spring. When you are done, repeat step 2-4 for the other two holes.

Step 4: Assembly back Cover

Slide the back cover on the Stand.
