Slapped this thing together to make programming a little easier. The modern Attinys use UPDI (one-wire) programming, so you only need three pins (data, pwr, gnd).
Adafruit sells the "UPDI Friend" that does the job for $6.95. I also found these pogo pin sticks at Aliexpress for about $2 each. Some minor surgery and I got the pin stick soldered directly to the UPDI Friend.
The only catch is these AliEx pin sticks are very fragile. The pogo pins are prone to snap off at the spring junction. I recommend ordering three of them just to make sure you get a solid one. Additionally, I used some UV resin to give the pins support above the spring line where it snaps off. I tried to get a closeup to show how it looks.
