This is a game/toy that I enjoyed very much when I was younger. I had to design it from my memories since I lost the original many, many years ago. Please correct me if I made a mistake in my design. Anyway I printed and gave it to my 2 testers (kids). Not too easy but as you'll get the feeling for it, it gets a fun replacement for the digital consoles (at least for a little while :) )
You will need a piece of rope/string to connect STL1 with STL2 (or STL3). Length between 30-50 cm depending on what you prefer.
Also if you curve STL1 (with hairdryer for example) it will make the game a lot more fun. I remember the original game had a curve in it. But I do not like the use of supports if it can be avoided. So I curved it myself, but I will add a curved one for those that prefer it that way.
1 point if you get it in the biggest hole (15mm)
2 points for the middle one (10mm)
3 points for the smallest (5mm)
STL1 + STL2 : Infill 20% will be about 2 hours and uses 26 grams of PLA. (That is for printing both at the same time).
STL3 is if you like it to be irritatingly difficult, definitely not appreciated by my kids. (rotate and print without support)
STL Curved will need support "touching buildplate".
