Test Tube Rack

This is a display test tube holder made for test tubes of a 20mm diameter. Assembly is as follows.

1. Print everything.

2. Insert the struts into the top of the base such that they lean into each other. (I should have designed it so that it could only be inserted one way. I should have done a lot of things.)

3. Insert the retaining pins into the sides of the base through the base and struts.

4. Align the top of the rack to the struts heads and push them through.

// This version is untested. I have recently added the retaining pins and the strut shelf to hold the head in place. This is in the process of printing on my end as I type this. Once it is QC'd on my end i'll either delete this note or add to it.
