This is based on the Screwless key holder by Marrrs. I create it in Tinkercad. The original was long for North American keys so I wanted to make a shorter version. I didn't like how the zip tie head did not sit flush with the inside and a space was required. I have short zip ties so it required an extra spacer. Now I can place the key ring spacer anywhere in the stack. Also allowed for spacers to have smaller holes or rectangular holes so they don't spin and move around. The zip ties are fed through backwards with this design and protrude slightly on the outer surface.

Modifications:

1. Modified the shape
   • asymmetric shape to easily identify which way to flip open the key by feel
2. Shortened over length to 82.5mm
   • because this was rebuilt from scratch I can alter the lengths
3. Change the way zip ties are installed so that they sit flush with the inside surface.
   • zip ties are installed in reverse to the original version
   • the zip tie ends are tightened through the surface rather than the ends.
4. Reduced/change the hole shape/size
   • reduced play for key ring attachment
   • spacing washers do not spin

Notes:

• Zip ties all have different dimensions. The ones I am using are from a dollar store. The head is 4 mm x 5.5 mm x 5.8 mm. Tail is 1 mm x 2.9 mm x 150mm
• 2 versions included: 1 ziptie and 2 ziptie.
