Tripod extension

Did it ever happen to you that your tripod was just a bit too short? Well, it happened to me when I tried to mount my DIY 3 element Yagi-Uda antenna (http://www.thingiverse.com/thing:1678158) vertically. Thus I designed this very low cost and easy to build extension.

This is what you need (bill of materials):
1 PVC-pipe (inner) diam. 20 mm, length is up to you
2 3D-printed parts (download above)
1 Nut: 1/4'' USC
1 Screw: 1/4'' USC, allen type, length 1'' (or longer and cut it)
Epoxy adhe
