I remixed this from the amazing holder by MetalThings. I did not need to many slots, so I made a smaller version. The pics are both renders, the model prints smoothly.
I used PLA and the standard 0.4mm settings that came with the printer profiles. I did not use rafts or supports. I used a Bambu Lab P1P.
