I wanted a cylindrical case for my TS100 but all of the ones that I found required the tip to be removed. I found one that I liked, but wanted it to have space for my extra tip and an allen wrench. For this remix, I scaled it up to 160% in the X and Y dimensions. I kept the top half the same length but made the bottom half 15mm longer so that there would be enough space for the other tip to fit completely in the bottom half. I then made cutouts to hold the allen wrench and the other tip. The entire thing fits together nicely although initially, it is difficult to screw together. There is also enough room where another cutout could be made to store another tip, although I don't have another tip, so I didn't add this design feature.
