I made this pinecil case inspired on the model by ithan over on printables. This version keeps the swiveling concept but has space to hold more tips (up to 5) and an extra space that I hope to make into a box in the future to hold some threaded inserts or something like it.

Feel free to make an addon on that spot yourself and share it with us!

It requires 4 10x3mm round magnets. Make sure you place them facing the right way.
