This is a remix on https://www.thingiverse.com/thing:3267115. Yelt's design is made for the Google Home Mini (V1) and this design is made for Google Nest Mini (V2). I increased the diameter of the base a little (because I couldn't fit my Google Nest Mini in Yelt's design) for smoother installation (and removal) and I changed the opening for the cable to a circle (I also removed Yelt's name from the model). Bar and bells are still Yelt's design.

I printed all parts with 0.10mm layer height, 30% infill, 40mm/s print speed & with supports (from build plate only).

I also made a printable M3 screw & acorn nut which you can use when you don't want to buy these parts. I printed them with 0.06mm layer height, 0.3 line width (I'm using a 0.4 nozzle), 100% infill, 15mm/s print speed, 5mm/s initial layer speed & no supports (print each screw & nut separately for better quality and use a skirt for each part). NOTE: if the screw and nut don't fit together, try printing (one of) them again. It can take a few tries before you'll get it right.

If you do want to buy these parts, you'll need to buy the following: M3 25mm countersink screw (2x) & M3 acorn nut (2x).

Installation is easy:
-(when using the printable bolts and nuts try first if they fit, you might wanna apply some pressure when screwing them together for the first time)
-Put both bolts in place (in the base) from the inside.
-Screw/put the bolts through the bells.
-Put on the bar.
-Screw (acorn) nuts on the bolts.
-Put Google Nest Mini in the base.
-Plug in cable from top (push the Google Nest Mini in the right position).
-Make sure the thicker part of the cable is stuck in the hole of the base part and not underneath for best positioning.
-Put the thinner part of the cable through the groove next to it.
-And you're done! :)

If you think your print is unstable, you can use the provided reinforcement rib, see the provided render for how to position it. I printed this part with the same settings as the base. You could also try to put a small rubber underneath this part to prevent the print from sliding when you're touching the Google Nest Mini.
