This is a handle I just made for my own Railcore ZLT door with magnets inside. I didn't think anyone else would want it but I've gotten several messages about it. I had to re-create the file as I lost the original model.
Uses 20x10x4mm magnets and has M3 size holes.
File Railcore Handle v2.1 - was for my 6mm thick panel
File Railcore Handle Mod - was for another user with 3mm thick panel and their hole for handle was 29.5mm from edge to center.
