Are You a keyboard person? Honestly it doesn't even matter!
If only You have a few mechanical keyboard switches You can print Yourself a perfect fidget toy - a Swidget! 
Also can easily be used as a keychain thanks to an integrated loop, that can accommodate almost any small carabinier that You could want from a lanyard or something and is also really strong.

Keycaps would also come in handy, but if You don't have those on hand I actually designed them too. The only thing You need to print them is 0.2mm nozzle.
Heavier, more tactile switches work the best. Tested with Gateron Low-Profile V2 Brown switches and NuPhy's low-profile switches, which are basically modified Gaterons.

Designed and oriented specifically for a process of 3D printing to create a strong, reliable part without the need for any supports.

1 or 2 switch variant is recommended as a keychain, because of high portability and 4 switch variant for best comfort, but of course You can use them however You desire.

Every variant is compatible with both profiles of switches, but you can choose which keycaps will sit flush with the border, or get rid of the border altogether.

I've created 4 print profiles:

• 1-5 switch variants for low-profile
• 1-5 switch variants for normal-profile
• 1, 2 & 4 switch variant, printed by object, for low-profile
• 1, 2 & 4 switch variant, printed by object, for normal-profile

This design is parametric, so You can customize it further yourself, by simply clicking "Customize" on the design's page.
This way, you can basically make a keyboard sword of sort, but then brim could be not enough and You may need additional supports while printing.
