This muffin liner press is designed to rapidly make muffin/cupcake liners for generic muffin/cupcake trays. The model needs to be printed twice in order to make the press.
You can make your own liners by cutting parchment paper in 6 x 6 inches squares, sandwiching one square between the two parts of the press, and then pressing the two parts together firmly. For stronger folds, you can experiment with a gentle twisting motion while pressing the two parts together.
The end result is a quickly repeatable liner with pointy corners sticking out higher than the muffin top, which gives each muffin a very stylish, yet homemade, look.
If you are a serious baker, consider printing this model 13 times. Then, you can stack and store them with 12 parchment paper squares sandwiched in between so that you have enough liners pre-made for your next batch of muffins.
Unlike some of my other prints, this one went very smoothly. I designed three versions of this muffin liner press starting by measuring the dimensions of one muffin hole in a muffin tray. I sketched two circles on two separate planes, created a loft between the circles to get the overall shape, and then created a shell of a couple mm thickness. At the time, my printer software did not offer the option to create a raft, skirt, or brim so I initially had a much wider circular base of 0.2mm thickness designed in to serve as a skirt. This was required because the printer had a tendency to knock down the model during the printing of the upper layers.
