Test Tube Holders -- with .dxf files

Pretty self explanatory.

I've mocked up two stands. [currently modeled for 16mm diameter test tubes. – I'll add files for 18mm and 20mm as well, if we need others, let me know :D ]

v1 - holds 12 vials

print [cut]:
1 each of p1, p2, & p3 (can substitute two p2 if you don't like the ears on p1)
2 each of p4 (end pieces)  

v2 - holds 6 vials + has drying pins (0.25in / 6.35mm dowels) 

print [cut]:

1 each p2
2 each p1 & p3 (end pieces)
6 each p4 (pin) [I recommend using wooden dowels because they don't always print nicely with such small profiles… and they will be a lot more fragile as vertically printed dowels]

I have it modeled to be printed and have included the .dxf files for those with access to laser cutters. sized for 1/8" (3.175mm).  

Also find enclosed, the .f3d files for those who need to modify it. ;)
