TS80 Case remix 3 tips

TS80 Case remixed from thing 3440265 by jacobgad. I modified it so that it holds an extra tip in the soldering iron. There are now 3 tips available for the TS80 so they can all fit in this remixed version. I like that I don't have to keep pulling the tips in and out of the soldering iron to store it as I typically use the same one very often. This means that the case is longer though because of that.

*** NOTE: The magnet size is changed from original thing ***

Changes from the original:
- Longer to add an extra tip to be left in the soldering iron
- Changed magnet size to 3x6mm (Those are the magnets I have)
- Offset the magnets so that the lid magnets stick out about 1mm so that it helps lock the lid in place. The lid magnets stick out 1mm. The top of the base magnets get inset into the base by 1mm.
- Removed some area in the center to give your fingers space to grab the tips and soldering iron
- Reduced width to make it narrower.
- Cosmetic change to the chamfe
