KIISU 4b Ultra-Slim Snap-Fit Case (Fastener-Free)

 

This is an ultra-minimalist, pocket-first protective case for the KIISU 4b development board. It focuses on maintaining the sleek credit-card form factor while adding essential protection and enhanced tactile usability. 

Key Features:

• Dimensions: 90mm x 58.5mm x 7mm.
• Ultra-Low Profile: Adds only 2mm to the board's native thickness.
• Toolless Assembly: Precision snap-fit design—no screws or hardware needed.
• Tactile Navigation: Sculpted interface cutouts allow for easy "blind" navigation by feel while in your pocket.

🖨️ Print Profiles Included

I have provided three optimized profiles for the best results:

1. Multi-Color + Logo: Includes a recessed logo and a white-painted LED indicator for light diffusion (AMS Required).
2. Solid Color + Diffuser: A single-body color with the LED indicator painted white.
3. Minimalist Solid: Standard single-material print.
4. Retro cassette: Two-tone design modeled after a cassette
5. Branded retro cassette: Similar to the standard retro cassette, just branded front and back
6. Retro famicom style: Inspired by the design of a famicom controller
7. Retro NES style: Inspired by the design of a NES controller

Recommended Settings:

• Filament: Bambu PLA (Standard or Matte).
• Layer Height: 0.16mm (Strictly recommended for snap-fit tolerances).
• Walls: 3 Walls.
• Infill: 15% Gyroid.

⚠️ Important Disclaimers

Filament & Brand Variance: This case is designed with tight tolerances for a secure snap-fit using Bambu PLA. Using other brands or materials (like PETG or ABS) may result in a fit that is too tight or too loose due to different shrinkage rates and flow characteristics. If using non-Bambu filament, you may need to adjust your flow rate or "X-Y Hole/Contour Compensation" in your slicer.

Hardware Variances: KIISU 4b boards are development hardware and may have slight manufacturing variances in PCB thickness or component alignment (especially the USB-C and SD slots). This case is designed for the standard V4B layout. If your board feels forced, check for any soldering burrs or misaligned components before snapping it in.

I'm in no way connected with KIISU, I'm just sharing my creation with all of you.
