Slide card wallet

v2. Modified spring mechanism to prevent falling out cards. Simple, minimalistic and compact slide card wallet. Very satisfying folding mechanism, can be used as fidget :) Max 5-6 cards. No tools and other hardware needed. Assembly: Insert inner part into hole on bottom half of wallet (45-90 degree angle). Then place top part in position shown on picture and snap everything together. After that it can be really difficult to slide the top part. Don't worry, just use some force and slide it back and forward. Small amount of lube on rails helps eliminate friction and help wallet to slide smooth. (I used a single drop of silicone oil on each side an everything works well) If it's still to much friction, use sandpaper. <span style="backg
