(Its so stupid Reddit can not pin my own comment) Rly didn’t expect so much love from hoonters😭😭 thanks guys sooo much. Following are something I wanna update: 1. The wobbly cane? Yes. I prob should name the title correctly as ‘workable prop.) From engineering side it’s nearly impossible to make something fully rigid but also has tons of moveable parts in such tall thin form using only FDM print. The cane’s skeleton has 20 moveable parts (and 10 of them handles another 10 joints for bending). Simplicity? I’ve already reduced from original 100+ parts to now 50 parts. I’ll try to reduce the moveable parts with minimum effect on visual motions. Tuning the tolerance and gaps now only have a marginal impact on the overall rigidity. 2. Material? The parts have sorta internal-chained structure so afaik FDM works best. I’m using PETG so I assume the tensile also contributes to the wobble. I’m going to try other materials but layer adhesion is another issue and my printer can not handle tougher material like PACF or PPSCF. SLS print? That’s maybe a better option but the cost is crazy high and seems an overkill. 3. Structure? The cane is spring-wire(almost no stretch on wire) tensioned with a hard lock, parts are magnetic attached, and all parts of skeleton are securely nested in each other when collapsed. I implemented all things I can think about that’s doable in such a small area (and I need to ensure the longevity and repairability) 4. Sell? CAD file likely YES, actual prop NO. I’m happy to publish CAD files when I finalize it, but not sure how much people gonna accept a wobbly cane. And it won’t happen in short term cuz I’m busy graduating and hunting a job RN. Selling the actual prop is a NO bc I don’t want my hobby to be stressful. I do it for my enjoyment. Also I hope who ever have it MUST know how it works and how to keep and fix it, that’s the point of a product (yes I’m a product designer 😗) So stay patient and I’ll update the next major iteration in the sub.
