I was tired of losing track of which volume I was on in any given manga series, so I made a little marker that can sit between them and let me know where I left off! The little fin slides between the covers and the labels tell me which volume I get to read next! No supports or infill required. I printed it on my FDM at .2 and the labels were… “legible” but I'm sure my printer isn't especially dialed in.

Thanks for checking this out!
