This bracket lets you bundle and attach two cables of 8 mm diameter each to a surface. There is a bridge integrated for a zip tie and the zip tie stays exposed to it can be removed and replaced.
Use 3M VHB double sided tape to attach bracket to surface (side of machine cabinet for example). I can recommend printing this with carbon fibre filled material or polycarbonate but PETG probably works just fine.
