About this 3D model

Nearly every 3d printed wallet is a hardcase wassel or card holder; thats okay but I'm not a fan of it and I also need space for cash and the change. So lets break down a simple normal wallet: its foldable space for cards space for bills and a coin pocket Alright lets take these four topics to design the perfect 3D printed wallet. I don't want a hardcase wallet and it should be foldable? Only solution here is, flexible material. so I choose TPU with a shore hardness of 95A Space for Cards and for Bills aren't that challenging. I just need to create small pockets which dont fuse together while printing. Thats how I came up with the design and Print orientation like it is. Closed and standing up. There are 3 Slots for 3-4 Cards each! so up to 12 Cards in total! The most challenging part to design was the coin pocket. I don't wanted to change the orientation of the model so I needed to fit it in like the model was set. I designed it so it can be enlarged by itself after printing. And also the lash ist coming down perfect so the holes for the buttons will just allign perfectly. I use this push buttons for the coinpocket, you can find it on Amazon . Since then I used it as my regular wallet and it survived without any damage. It just got a little bit dirty over the time while i tested it by using it every day! Print it standing up, like it’s orientated in the file. Use a brim to get better bed adhesion! Use 2 Perimeter and Infill around 30%, no Support and ofcourse use TPU
