Print instructions

I have no printer so I cant check functionality righ away so its maybe more about the idea than about the print itself. UPDATE - I was able to print the test print and it works(without supports).

It should fit to the 1CZK coin - it has dimension 20( diameter x 1,8mm(thickness). So it should fit also to 10 euro cents, 2 Zlote etc - but I suggest testing before the printing of whole part-there is also test print with only one thread.

Idea is to throw coins from upper side and it should run in groove to the bottom. And it should be usable also as a pencil holder or lamp shade. Ive created much bigger groove so the coin should travel freely now. In case you would need supports you can change the thread pitch to higher but then you will need to upgrade also the positions of the holes.
