KIISU V4B Case

Protect your KIISU V4b like a dragon preserving all its functionality intact.

V1.0.2 (latest)

Meet the KIISU V4B Case — the sleek, no-nonsense (but still fun!) case your KIISU board has been waiting for.
Since the KIISU is so thin it feels like you could lose it between two sheets of paper, this box comes to the rescue: it protects the board without turning it into a brick, and keeps all KIISU features fully accessible. Minimalist, practical, and ready to print.

V1.0.1 (old)

Print it at 0.20 mm in PLA or PETG, with no supports, no screws, and absolutely no hassle. Just print, pop in the buttons, snap it together — done. 

✨ Features

• Slim and sleek design — protection without the bulk

• External buttons for easy KIISU control

• Front and back GPIO access — because you’ll always need “just one more pin”

• Easy access to the Power button

• TF card slot access for quick swapping or flashing

• USB-C port fully accessible — plug in without fighting the cable

• Compatible with RF and Sub-GHz transceivers

• iButton easy access — why most cases hide this functionallity? I don't.

• Light-sensor hole to keep all functionality intact (new version - need to update my pictures)

• Easy battery access for fast replacements

Update V1.0.2 (2025-11-26):  Better, now with thick walls, slimmer and more resistant. Also have a better protection on iButton (thanks 2elw for your recomendation).

Update buttons (2025-11-27): Now you can print all buttons linked by integrated spring to avoid the use of tape and simplicity of mounting them. You can these buttons in TPU for better touch and spring function but in PLA por PETG should do the work too.

New variant with antenna: v1.0.2 with external antenna cut - not  yet tested but should work. / download only if you have soldered external antenna conector.

Notes: Print with 3 walls. Reduce button size by 10% if they fit too hard (depends on printer and filaments).
