Quality spacers and solved the issue I needed solved.
I am going to build a Jupiter this weekend and I was wondering if you could use these on the backside of the motor (with the tabs that you solder to) to prevent a short circuit. I'm exceptionally bad at soldering, and as I watched your build guide for the Jupiter, I noticed how you mentioned being careful not to use too much solder when soldering to the motors. I personally think this could be a perfect solution! Would you recommend it? Thanks.
