Piwars balloonholder

This is a 3D printable version of the balloon holder for the pi-noon part of the Piwars challenges (piwars.org). It is not an official Piwars holder, just one I made to allow me to practise jousting balloons :-).
It has been configured for a 2mm thread that you make a length of 17 cm and the other length should also be 17 cm.
The freecad design file is also present so you can adjust the design for another kind of thread.
You can add a little tape at the bend part to make the clamp fit tightly.
Use two 3mm bolts to clamp the thread.
