Gothic test tube holder (also for regular test tube)

Hello there,

i was looking for a test-tube holder that could be printed in one piece without supports and was also a bit bigger so that the full test tubes would not tip over (and take the holder with you right away).

I found some interesting holders, but I had problems printing them all the time. Either there were cavities, for which I had to print supports again, or the holder has to be assembled and glued.

I created the model myself with OpenSCAD. The gothic arcs are for printing without supports (and look cool ;-). I also put the previous version online, but I only recommend it if the test tubes have a diameter below 16 mm, otherwise they won't fit.

testtube-stand_gt_16.stl -> use these for test tubes greater than 16 mm. Also in Gothic style to prevent stringing on the bridges.

testtube-stand.stl -> use these for test tubes that are 16 mm or thinner. My first try, but my test tubes were to big for this holder.

I hope you like it.
