I made this model for my fathers label printer, it fits 4x6 labels and has a crossbar for labels on a roll. The cross bar has locator pins to keep it from sliding. The extended version was my initial design but was too long for my mini+ so I trimmed it down, I've included both versions but I have not printed the longer one, post a make if you print it. The short variant I printed in Prusa's galaxy black at 0.2mm layer height with no supports which took 20.4 hours to print. All models are designed to be supportless.
