There are other Swiss Army-style keyrings, but these are mine, inspired by Laura Kamph on YouTube. There are three, all pretty minimal. There's a separate printable hanger piece to let you attach something that's too big for it, like, say, a car remote, though you will still need a metal ring to link the two.
(Tho' this thing attached to a car remote would pretty much make this your key fob, lol)
The three are 1: a minimal no-filing-required key holder, 2: a much flatter bike-key-format key holder, and 3: a flatter house-key-format key holder that requires filing down keys to the stops. There are three sizes of Version 3, two different lengths and two different widths; which you want to use depends upon the number of keys you have. Three or less, try the smallest with all the keys on one end. Four to six, use either the middle size or the longest size depending upon how big your keys are.
There are also 2mm spacers, as well as caps for bike keys and standard keys that you've filed down. The filed-down keys don't absolutely have to have caps but the nubs on them make them much easier to single-handedly flip them out of the holder. The bike keys, once the original plastic heads are removed, absolutely require the bike key caps.
Everything uses 4mm holes all around so if you're in North America you can use a 6-32 wall outlet bolt, for which it's countersunk for both the head and the nut. If you're working in better units, obviously use a 3.5mm bolt instead.
The indented squares on the sides of types 1 and 2 are for printing some sort of glyph separately (so you can go multi-colour if you want) as a label. I just use a picture of a house (included, set up to be easy to print multi-colour with a single-filament printer) and a glyph of a bike for the type 2. There's not really room for this idea on type 3 though.
For type 1, I've included left and right versions so you can put the screw head and nut on whichever side you prefer. (For some reason for me this has a handedness and I don't know why. But it does. It's 100% the same, just reversed; you could also do it in the slicer. But I give you both.) For types 2 and 3, I didn't, but you can just flip it in the slicer.
