I bought a Prusa MK3s during lockdown (don't think I'll do the upgrade to the +, doesn't seem much changed), it is amazing. I've never owned a 3D printer before, and it was painless to put together, took about 1 hour to tune and fix one assembly glitch. It's sitting right next to me printing right now.

The other thing I bought myself was an M1 mac. I just got frustrated with cleaning my butterfly keyboard again, and just said, "fuck it, I'm buying one". It is an amazing machine. Battery for days, nice, light. It's probably my favorite computer ever (well, after my first – an Apple //e).
