Tired of your flashcards getting smudged, soaked, or bent out of shape? The Flashcard Protector shields your cards from dirt and moisture.
Designed for both storage and study, it offers reliable protection even when you're flipping through cards with damp fingers or on the go.
This model was designed to fit flashcards I created by manually dividing a standard letter-sized sheet (8.5 × 11 in / 216 × 279 mm) into thirds vertically (approx. 72 mm wide) and eighths horizontally (approx. 34.9 mm tall), resulting in a grid of 24 uniformly sized cards per sheet.
However, every flashcard is different. That’s why I’ve included the Fusion 360 source file—so you can customize the design to match your exact card dimensions.
| Parameter | Value (mm) | Description |
|---|---|---|
length | 80 | Total length of the flashcard cover |
width | 40 | Width of the flashcard cover |
hole_x | 14 | Horizontal offset for the hole position |
hole_r | 5 | Radius of the hole |
corner_r | 3 | Radius of corner rounding |
thickness | 1.2 | Extrusion thickness |
side_r | 12.4 | Radius for side rounding |
fillet | 1.2 | Fillet for general rounding |
fillet_top | 0.5 | Top edge fillet |
fillet_hole | 0.5 | Fillet applied to the hole edge |
I recommend printing with TPU for a flexible, long-lasting shield that won’t crack or warp under pressure.
