key organiser

this is a key organiser fitted for my need:
(sorry for my english)
My problem which leads to design it, was the specials keys for 3pts lock door (cylindric + ''star'' ended) and garage door. As the special key is not regularly flat and very thick, it was impossible to put it in commercial key organiser. So mine is designed to accept the special keys. As there are many different key shape, I give the idea to help you to design yours.
the washer as key separator are different thickness 5, 6 7 or 8 mm (it was my need, but in Cura you can stretch it in the desired axis).
to assemble all, I used 2 screws: M2x30mm screw + 2 hex nut.
for a safe assembly (no risk of disassemble) I used thread lock.
I used generic PLA filled 35%, top bottom 6Layers, wall lines=6.

remark: don't take care of the section ''Print Settings'': impossible to fill with the correct options (maybe an issue of Thingiverse).
