README for the flippers.

We recommend you use a 12mm deck.  So use the 12mm files.

USE ABS or another impact resistant material for the flippers as these take a beating.  We also suggest the use of ABS for the files "Double Drive 12mm Deck Mirrored" and "Double Drive 12mm Deck".  The solenoids will get pretty warm if you hammer them and normal PLA may soften.

The Flippers:
- Flipper 90 and Flipper 90 plus 1 and 2 - are for 9mm decks
- Flipper 90 Plus 3 and Flipper 90 Plus 4 - are for 12mm decks. We recommend the plus 4 file
- Print these in ABS with 5mm wall thickness

The remainder can be pla with moderate wall thickness. Though we want the following to be solid PLA:
- Double Drive - Driver
- Double Drive - Limiter
- Solenoid Coupling
