RC Spring Cups (D5, CC-01)

Ever lost a Tamiya D5 spring cup (like on Tamiya CC-01)? They are cheap and easy to come by, but it's so annoying to wait for the delivery...so why not making them yourself?
And now the cool thing: You won't ever loose them again - thanks to Roland's great idea - we use a screw to secure the cup!

It's customizable, if f.e. you want make them fit other chassis/dampers/shocks.

The STLs with screws use a M2 screw.
