I have sketched out a small, spring-loaded golf-ball dispenser that clips onto any standard golf bag, and I’m ready to move from idea to detailed design. Picture a scaled-down golf bag made from synthetic leather – the same look and feel you see on premium caddy bags – sized just right to hide three balls inside. A front-mounted push button should trigger an internal spring so one ball pops cleanly into the golfer’s hand. After each ejection the mechanism must automatically stop the remaining balls from slipping forward and re-seat the next ball so it is ready for the next press. Core requirements • Capacity: exactly three regulation balls in single file. • Materials: outer shell in durable synthetic leather; interior components may use plastic or light metal if that simplifies the spring action. • Colourway: initial production mainly black or white; we will over-print brand logos and custom text later, so smooth, print-ready panels are essential. • Mounting: a secure, one-hand quick-clip or strap that lets players attach and detach the unit from any golf-bag ring or handle. • Button feel: crisp, consistent travel that works with golfing gloves on. What I need from you 1. Full 3D CAD of the housing, latch, and spring path, including assembly drawings and exploded views. 2. Material and component specification ready for quoting with manufacturers (synthetic leather type, internal plastics, springs, fasteners). 3. Simple proof-of-concept prototype files (STL or STEP) I can 3D-print for fit testing, plus guidance on lining the shell with synthetic leather once the form is confirmed. 4. Short BOM and assembly guide that highlights critical tolerances to keep the one-ball-at-a-time action reliable. I
