SlideWallet V1

NEW VERSION 2 : link

After releasing two print-in-place card wallets, I decided to take a different approach for my next design—this time, not print-in-place.

I revisited the drawing board and developed a brand-new design with an innovative mechanism I haven't seen before. This version features a unique downward sliding motion of the front face, which causes the cards to pop up effortlessly.

The wallet consists of just three parts that snap together without the need for any additional hardware.

To ensure smooth operation, this print requires a highly precise and well-tuned 3D printer. Some light sanding may be necessary to achieve frictionless movement between the components.

Assembly Instructions:

1. Lay the base down, and position the inner part, called the "cascade," onto the pivot in the closed position (as indicated by the groove in the base).
2. Place the slider on top and snap it into place.

Printing tips :

• Material: I’ve tested both PLA and PETG, and I prefer PETG for its smoother operation.
• Nozzle: Use a 0.4mm nozzle with a 0.2mm layer height.
• Slicer Warning: You may receive a warning about a floating cantilever—this is intentional. It refers to the spring mechanism that holds the cards, which is raised one layer above the base to allow for free movement.

I understand this model might not be for everyone, as it requires precise printing, some sanding, and a bit of use to achieve a buttery-smooth operation. It won’t be perfectly smooth straight off the printer—it needs a little fidgeting and handling to break in.

However, if you successfully print it, enjoy! I’m proud of this deceptively simple design with its intricate mechanism.
