Slim 6-Card Pop-Up Wallet with cash storage

This is a complete redesign of the original Pop-Up Credit Card Wallet Spreader with Coin/Cash Storage by Mike. I recreated every single part from scratch to make it slimmer, stronger, and more practical — without scaling the original model. 🔧 Key improvements Reduced dimensions: from 103 × 68 × 17.55 mm → now only 101.5 × 63.2 × 13 mm , making it noticeably thinner and more pocket-friendly. Still fits 6 cards — the pop-up mechanism remains fully functional. Cash compartment: fits up to 2 folded bills . New spring mechanism: redesigned for a narrower body while keeping reliable card tension. Closed front window: prevents dust and debris from entering the card chamber. Honeycomb texture: added on both sides for improved grip and aesthetics. Front panel includes a removable insert with the same honeycomb pattern. The raised ridges between the hexagons protrude by 1 mm for tactile feedback. Fasteners: uses 6 × M2 × 10 mm countersunk screws with matching nuts. 🧵 Printing notes Recommended material: PETG for flexibility and wear resistance. Layer height: 0.2 mm , 3 perimeters, 15–20 % infill. No supports required for most parts (depending on printer tolerance). Assembly is straightforward — use the included screw holes for alignment. Update 25.02.2026: Added Middle Part v2 with reinforced spring for stronger card pop-up force and improved reliability.
