Logitech K400 Narrow Key

This is a narrow replacement key for the Logitech K400 keyboard (Not to be confused with Logitech K400+ which uses different keys), derived from [Logitech K400 Key](https://www.thingiverse.com/thing:4643651/remixes) by lc7ineo.

Since the clips are so small, I reinforced them to make them more sturdy although still flexible enough for inserting the keycap. There's also a print-friendly variant that does not need supports (see comparison screenshot).
