The rounded Gearwheel!

It may well be I'm the only one interested, but I finally got to produce that 9 teeth, rounded Gearwheel I mentioned...

And here it is:

You can resize it to any radius, and teeth number, and it's always the same routine, see the tooth tip part, upper right?

You glue it to the base, aligning the thing to the tooth's tip, then glue the tips of the 2 long parts to each adjacent part going up 90º from the base.

Repeat until done...

Then add a central paper ring, for reinforcement...

When done, add the upper part!

No big deal, assembling this! :)
