fidget spinner bicycle chain hello, here is a small fidget toy. base is a chain that is built like a bicycle chain. the fidget has a size of 56mm x 26mm. good for playing in one hand. you need 32 chain link plates, 16 rolls, 16 pins with caps. a pair of holders (start with 41mm) and 2x sprockets. the pins must go easily into other parts or it won't work. i finished the holes with a hand reamer to remove z-seam and print residue. the bolt must be printed in such a way that the cap can just be pressed onto the bolt. then press it together with water pump pliers. this holds the cap very well, even without glue. just test it. make and close the chain completely. then insert the sprockets and screw them with the holders (M3x12mm). there are two versions for the sprocket. with and without ball bearings. you need 2x 603zz (3x9x5mm) for the ball bearing version. my recommendation is to use the sprockets with the ball bearings. there are different lengths of the holders. depending on how much play the chain has, you may need a different length. the chain should have about 5mm play when you pull it sideways. the links should help to understand and find the parts and tools easier: https://aliexpress.com/item/1005004015357414.html https://aliexpress.com/item/32951062612.html have fun printing, assembling and playing. https://youtu.be/Mmymwdd0zpk
