Free glasses case

In this project, I created a modular spectacle case where the magnetic closure and the hinge are always the same. I designed three standard sizes that include CAD data (FreeCAD and STEP) so individual cases can be made. The recommended material is PLA or PETG. The following non-printable components are needed: - Two 3mm x 60mm metal rods for the hinge. I used brass, but aluminum or stainless steel will also work. - Fourteen M2 screws that range in length from four to ten millimeters. Six millimeters is recommended. - One to two pieces of felt, each about one to three millimeters thick. - Two to six magnets, each five by eight millimeters in size. - Glue. Assembly: First, the felt should be shaped into form. Soak it in warm water for fifteen minutes and then press out excess moisture. Place it in a container or mold. The felt can also be pulled apart with some force so that no creases are formed. Let it dry in the mold for about twenty-four hours. Once the felt is dry, it can be firmly pressed into place and any excess felt can be cut off. It's best to do this in several stages, cutting more and more downwards each time. Next, the hinge can be attached by screwing it onto the case. If there are material fragments inside the hinge or if the print isn't clean, the holes should be drilled out with a 3.2mm drill bit (included as a core-drilling bit for M4 in every standard HSS drill set). Finally, the magnets can be inserted opposite each other so they attract each other. The number of magnets needed is up to individual preference, but two is somewhat weak and six is relatively strong. I would greatly appreciate it if you could donate a small amount or send me a picture of your print. You're also welcome to visit my other designs at Thingiverse.
