Just a simple multilevel Hexagonal Key tidy.
There are 3 heights of key fob to match the varying heights of the holder. Below are the quantities of each you would need to print to fill the holder but I think it looks better if you leave some gaps
x4 - 15
x11 - 20
x4 - 25
Depending on your printer you may need to scale the print to fit on your bed.
Technically there should be a 0.1mm gap between the fob and the holder but I had a slight issue with the squish effecting the fit of the fobs into the holder so I scaled the fobs slightly more than the holder.
I scaled to;
Holder = 70%
Fobs = 68.5%
Just because I preferred the smaller fob size for the keyrings.
I have added a v2 holder to fit the 15mm key fobs. That way you can print all 15's.
I have also added a v2 with holes as i know someone mentioned mounting it on a wall.
