This model is a cable guide / cover for a 19° rack.
The model can be downloaded in its entirety or for the Bambulab printer.
The version for the Bambulab printer consists of 3 parts that are connected together. The 2 main parts are plugged together and can be glued to the connection plate if required.
Have fun with the printer :)
More parts for 19° racks will be available soon under my profile.
