Small solutions
My daughter is special needs, having genetic disorder 1Q21.1 duplication syndrome. One of the quirks of this disorder is she’d like to run around while eating. This leads to risks of choking, risk of impaling her mouth roof/cheeks/gums, poor diet as she can essentially pick through what she wants and skip eating anything good for herself, and a degraded hygiene for her and anyone else in the house as food tends to get in carpet, furniture, and anywhere else it can be dropped or kicked.
I’m a career fabricator with 20+ years in fabrication. Looking for solutions, the only one realistically on the market is the safety harnesses made for vehicles for special needs. They are somewhat expensive, often turned down by insurance, and using them during meals would require them be washed for hygiene which would degrade their performance and safety factor. Not to mention figuring out a mount point for them anyways on a dining chair. I had to come up with a solution that could be easily iterated on, repaired easily and replaced easily without costing a fortune. My solution and voyage into 3D printing was this.
It’s printed in ASA, 100% infill, 13 hour print time give or take and printed on an Ender 3 v3 KE. Modeled in Freecad. I’m already on a version 5 as I fine tune the design so works a little more seamlessly.
This buckle has allowed us to get her to the point in one week where she’s actively wanting to sit and buckle to eat, eats her whole meal, lets us know when she’s done and has reduced mess and waste by a 80-90% margin.
