Minimalist A6 Postcard Holder

Keep your favourite postcard on display and your collection right behind it.

SHIFT / 08 combines a single-card display with a storage compartment. Two thin walls with opposing diagonal edges create an asymmetric silhouette, while open sides and narrow guides keep the focus on the postcards.

The front postcard slides in from above and sits in portrait orientation with an 8° backward tilt. A 15 mm rear base extension adds stability. The holder prints as one piece, with no assembly required.

Files and customisation

Use the STL for slicing. The OpenSCAD source allows you to adjust postcard dimensions, storage depth, wall thickness, and tilt angle.

The mesh has been checked for integrity. The model has not yet been physically test-printed, so print settings and fit still need verification on your printer.
