Decorative test tube vase base

This is a print-at-once version for test tube vase base. The original version was made of two twin parts and was made this way so it can be filled with concrete to give a vase some weight since it was originally painted with texture paint so it would look like a stone made. I linked a video on "How I designed this" to original design.

Test tube that used is this one from IKEA called RIMFORSA (https://goo.gl/f5KwoB)
