Mechanical Smart Wallet

cults3d

This is a Smart Wallet with a unique mechanism. It uses a push button to present up to 6 cards. The cards are securely held in place by a small hook that automatically opens and closes. On the front of the wallet is a clip to hold some paper money. Dimensions: 76x100x16mm New and improved design here Parts required: 5x M3 10mm button head bolts 2x M3 12mm countersunk bolts 7x M3 Threaded Insert (optional) Thin elastic string 1x Shell 1x Cover 1 1x Cover 2 1x Button 1x Hook 1x Link 1x Riser Assembly: 1) Remove supports and install the threaded inserts for the shell and first cover. 2) Thread elastic string through the small hole in the bottom of the button and tie it into a small loop. Connect the button and the riser using the link. 3) Insert two countersunk bolts through the rear of the shell. Then, place the hook and riser assembly on the bolts. Stretch the elastic string over a small peg inside the shell. Place the first cover on the shell and tighten the bolts. 4) Test the mechanism. The cards should move up and down without any resistance when sliding the button. If the button doesn't slide back, slightly loosen the bolt for the riser or use a smaller loop of elastic string. If the hook doesn't close freely, slightly loosen its bolt. If the hook starts to close before cards reach the bottom, lightly sand the part of the button that closes the hook. 5) Press the 2nd cover over the first one and secure it with 5 button head bolts. 6) To insert cards for the first time, push the button up and use the corners of the cards to open the hook, then let the cards fall into the wallet.
