Marble/ball maze
Replace the cellphone with something equally fun.
This maze never ends, where one seemingly ends, a new one begins, and so on and so on and so on...
Too easy with one marble? Put more in and you'll see :)
mine with 5 balls cause me more pain and stress, than relief :D
Made in two sizes.
5mm ball - typical ball bearing
6mm ball - ball bearing, BB or airsoft ball etc.
for fully assemble insert ball to hole on side and secure with M6 (for 5mm ball) or M8 ( for 6mm ball)
