DDT 2.0 (Das Demo Tröte)

The idea was to print as sparsely as possible for a demo on 1. Mai in Leipzig.
Embossing a Message on the cylindrical surface is implemented.

Uses < 14.00g of Filament and not more than 5.00m.
Prints 20 pieces in under 18h and use the Filament efficiently.

A Band is a neckband is attachable. 

Span a sheet of latex glove between the two parts.
Should sound like a tiny drum.

Also one can adjust the print time and run a time efficient schedule  by using for example 12 Cans and 6 Covers 10 to 11h when at Work and start a print with 6 Cans and 12 Covers over night 7 to 8 h.

Instructions on how to use the implemented cylindrical text wrapping function is described in detail in the *.scad -File. 
It prints well in Draft mode (0.30mm layer height) so mass production prior to events is easy.
50 to 60 min for a set.
