domekit 2V

Description
These are parameterized connectors for building small domes for learning. They are based on effalo's V2 dome kit.
I have re-written the scad files so that now it is possible to make small connectors that work with wooden sticks of very small diameter (3mm or less).
I have tested it building 2 domes that I've called as Mini-dome and Micro-dome, with diameters of 50cm and 15cm respectivelly. I have used wooden sticks with section of 3 and 2 mm, that are very cheap and very easy to find.
The connectors are parameterized. The user has to introduce the stick diameter (in mm) and the holedepth. The size of the connector (radius and height) will be automatically calculated.

Instructions
You can calculate your own stick length according to the total dome's diameter requiered:
simplydifferently.org/Geodesic_Dome_Notes?page=3#2V/L2
I have precalculated 2 examples.
Example 1: Micro-dome
* Diameter: 150 mm
* Height: 75mm
* 20 x Hexa-connectors
* 6 x Penta-connectors
* 35 x Long sticks: 46.3mm (Green)
* 30 x shot sticks: 41mm (Red)
Example 2: Mini-dome
* Diameter: 50cm
* Height: 25cm
* 20 x Hexa-connectors
* 6 x Penta-connectors
* 35 x Long sticks: 154.5 mm (Green)
* 30 x shot sticks: 136.6 mm (Red)

This is the perfect basestructure for a electric-fence safeguarding ones NOM.
Now to find a Free hardwaredesign for the former.

I need one of these. I want to be that happy.
I loved it when the printrbot turned into an "Armored Volumetric Entity Making Spherical Unit" in that photo.

I love the picture, you seem so happy it is almost contagious, and you know that we can use some happiness in our country right now.

When I try to render this part on Repetier with slic3r it just shows up as crosses that the machine prints. How do I render these STL's?
Nevermind, I have sent then to Netfab, now they are repaired and it works fine! Only, I think I am printing them a little bit too fast.. Just got a new hotend, and am still testing it's limits hehehehe.
