Vỏ Cuộn Thiếc Hàn

This is a sleeve that fits over common solder spools. I was irritated when the solder would unspool and get tangled and this seems to be a good solution. Mine fits MG Chemicals spools but I will include the A360 downloadable file that will allow the parameters to easily be changed to whatever size you need.

Update, the Fusion 360 file has been included so that you can modify as needed.

To customize for your size of spool, download the Fusion360 file. Go into the parameters table. I have labeled the only two parameters you would need to change...RollDiameter and RollHeight. Allow a hair extra for a comfortable fit.
