Simple model of a keychain or backpack tag in military (or cyberpunk/futuristic) style. Prints quickly, is lightweight, requires little filament. Designed to fit a standard 25mm wide webbing or strap.

The original idea is designed to use self-adhesive reflective tape as a color layer, but instead of it you can use a light-accumulating tape, any piece of plastic that you like in color or print it (file *_Color). Each tag consists of two parts, between which the color layer of your choice is clamped.

 The base and the top plate are tighten with M3x5mm screws (DIN 7380/ISO 7380) or you can buy nice screws on Ali (links for example:

You can optionally make your own design of the top plate - for this, step files of the top plate are attached. any remix is allowed, feel free to create, you can give away and distribute physical copies of these files for free, but selling finished products or digital files without permission is not allowed - commercial license can be negotiated separately.
