hen I started to think how it is working (without knowing all the parts) and then I made my version. You will need to print: - one bottom part (or bot_3 for 3 rings) - top (or top_3) (this one needs some supports, set it to 'everywhere') - locking_ring (you can print locking_ring_tool too if you will have some problems with rotating the ring with fingers) - 3 or 7 ring_inside and ring_numbers Printed with 0.4mm nozzle with 0.2mm layer height. May need some sanding for smooth use but remember that ring_inside should go in the ring_numbers with some resistance. Changing the lock number may be little difficult sometimes. Just take the ring in hand and push out the ring_inside part a little with sth flat, then rotate it in hand a little and push again and rotate and push Cryptex assembling animation: https://youtu.be/2dgY8XxDOcI2b:T7ea,'/2dgy8xxdoci':210B '/en/3d-model/game/clicking-modular-life-counter':44B '0.2':139B '0.4':135B '3':87B,89B,94B,125B '7':127B 'a':186B,196B 'again':200B 'all':68B 'and':71B,130B,179B,198B,201B,203B 'animation':207B 'assembling':206B 'base':37B 'be':169B 'bot':86B 'bottom':83B 'but':150B 'can':9B,24B,107B 'changing':164B 'clicking':2A,6B 'coins':17B 'counter':41B 'counting':28B 'cryptex':3A,7B,51B,205B 'cults3d.com':43B 'cults3d.com/en/3d-model/game/clicking-modular-life-counter':42B 'difficult':171B 'e':55B 'e-shop':54B 'etc':19B 'everywhere':103B 'fingers':124B 'flat':190B 'for':27B,88B,147B 'from':36B,47B 'full':14B 'games':34B 'go':156B 'hand':178B,195B 'have':116B 'height':142B 'hide':10B 'how':62B 'i':58B,73B 'idea':45B 'if':113B 'in':13B,32B,52B,157B,177B,194B 'inside':20B,129B,154B,184B 'is':64B 'it':21B,26B,63B,101B,193B 'just':173B 'knowing':67B 'layer':141B 'lenght':15B 'life':31B,40B 'little':170B,187B,197B 'lock':166B 'locking':104B,109B 'made':74B 'may':143B,168B 'mm':136B,140B 'modular':39B 'money':12B 'my':75B 'need':79B,144B 'needs':97B 'nozzle':137B 'number':167B 'numbers':132B,160B 'of':38B,50B 'one':48B,82B,96B 'or':22B,30B,85B,92B,
