Sorry for not posting the spacebar design at Thingiverse. The prototype I printed for the space key on September wasn't quite satisfactory. I revised the hooks/holders but didn't have the time to print a new prototype. I'll try to do it in the coming days and upload the files if everything turns to be working.
@tech, did you finish the model of the Space Bar? Would be nice to see it in your repo.
I'd be curious to know how well these things hold up over time. My experience with heavily-utilized 3D-printed PLA doesn't fill me with much hope.
If you're not happy with PLA just use ABS, no big deal.

PLA that I use (Tianse, Patona) seems to be quite good when it comes to the replacement of some keys. If you avoid hitting the replaced key with your fist, it will hold for quite some time. And if it eventually breaks, getting the replacement is just 15 minutes away.
I've made the 2-component set of keys that fit Yamaha MSX1 and MSX2 computers (503, 805, 604, CX5, CX7). The outer shell is printed on an DLP printer, the inner part - on an FDM printer. The outer shell is reworked so that the gaps for letters are filled with the material of a different color and then it's hardened under UV light for 5 minutes. Some minor polishing with a nail polisher bar and you have a key that looks almost identical to the original.
The key set can be found here:
