Playing card holder

A stand for playing cards, designed especially for kids who can't hold the cards in their hadns yet. It can stand on a tabletop or the "middle leg" of the frame can be held in a hand in a similar way playing cards are normally held, which should help the kids learn the "proper cardholding technique" :)

Perhaps it will help someone keep their family entertained during the COVID isolation :(

I haven't tested it yet since I'm still waiting for my Prusa MINI to arrive. Be brave and be the first one to test it!

**The stand consists of three parts**
- Frame

- Middle plate – it holds the cards with its springiness, so it needs to flex. Four versions are available, with 0.44 or 0.87 mm thickness (i.e. one or two perimeter(s) with 0.4 mm nozzle) and with 2 or 3 mm spacer (determines maximum thickness of the cards in the holder). Choose the one that suits your needs, mainly filament choice will affect which thickness you need to achieve the right amount of flex.

- Front plate – t
