When i was young we used to play a lot with Forza 4 (italian name) but i lost the original game a lot of years ago, so i decided to make a reproduction to play it again :D

Try with just one coin first to see if the tollerances are ok in your 3d printer. If not just scale the coin on z axis ;)

There is no need of support but if you prefer you can add some under the holes to help the bridges :)

No support needed. Use 100% fan and you will be fine :)As material choice PLA is a classic. The original color was blue / light blue type (99% sure it was ABS).You can try to print it in PLA WOOD to get a really vintage old school look. It would be awesome :D
