Giá đỡ cuộn thiếc hàn dọc v2

There are plenty of Solder Spool holder models that hold the spool horizontally, but I wanted one that kept it upright, so I designed this one. 

To assemble, you need one 8x22x7 mm bearing (standard skateboard wheel bearing) and a m3 x 16mm machine screw. Click the bearing into the bottom piece and then click the top piece down onto it. It should be a snug fit, but not insanely tight. Then use the washer and m3 screw up through the bottom into the center pin on top. I would recommend adding some rubber feet to the bottom for additional grip to your table top.

I have included the .step file for easier remixing or if you need to adjust that top spool pin. It's 18mm in diameter which is perfect for 1 pound spools of Kester solder.
