Flip Scoreboard

All parts are very easy to print. Most parts are replaceable for different scenarios. 

• Overall size 220x115x150 mm (LxDxH). 
• For the rings, you may want to use steel key rings instead of the ring.stl I provided. If you don't have any steel key rings you may consider using my ring.stl and then use a soldering iron to close the ring after putting it through all the number plates. I would suggest ring inner diameter of 26 mm. A ring too small may cause difficulties to flip the numbers. The last option for the ring might be cable ties. 
• For the stand, you will need 6 nos. of M3 heat inserts and 6 nos. of M3x8 screws. This stand is not very strong since I would like to save some filament. Looks weak but quite enough for me. 
• For the number plates, you may consider using multiple extruders or simply paint them as I did.
