PLA can melt, so print it in PETG.

Only buy these after soldering the wires. and make sure the wires are all the same length because a high speed is necessary.

and buy these cables after you solder the breakout boards together

because you need only 2; the rest are just in case you soldered one of the breakout boards backwards
