Soldering electronic components using a large solder spool of 454 grams or so is quite inconvenient even if it is mounted on a solder spool holder. I prefer to wind a small amount of it on a smaller spool. This is what this mini solder spool is for. It can hold about 75 grams of solder wire.

Print one of each part and screw them together. You can use an electric drill at low speed to wind some solder wire on the spool. A bit of advice, use a small tube to guide the solder on the spool. Do not use your fingers especially if the solder contains lead.

I suggest using at least 30% infill.

Support is not needed.
