5 and 10 ILS coins + holder for shopping carts

Took care of the following:

• No more printing on the air (proper overhangs limited to 60 degrees)
• Smaller footprint
• Springy lock step for the coins (to avoid relying on friction only, coins pop in and out)
• Proper angled form for 5-ILS coin

There is a file containing everything (coins_with_holder), and separate files for holder + coins for whoever wants separate items.

Printing instructions: 3 walls, 0% infill, no supports.
