There are 2 versions of the Sinclair ZX Spectrum case; a first 2 parts for printers that have the ability to print large pieces; and a second version of the usual 4 piece bed 200x200mm printers.
This case is a traditional approach to the original model. No fingerprints for rubber feet. And the angle of the serigraphed sheet keys not coincide with the main bevel of the case. But as you can see in the photographs, it is mountable.
