Book Binding Hole punching Jig

Simple jig designed specifically for the A1 Mini. It features a 5mm small wall, with all holes positioned 5mm apart. The holes have a 4mm diameter and a tapered angle, ensuring compatibility with various tools while maintaining precision. The photo includes handwritten notes showcasing a pattern I prefer.The model is split into two files, one for the base and one for the top.Let me know if you need specific dimensions. For the 9in version, I linked STL files (I have the A1 mini, so I cannot test those) - send me a message if you have issues.
