Do some 3D Modelling

Design of a pcb enclosure with a unique design. Best way to explain is do a quick google for "commodore 1541-II drive" and "sd2iec". The first is a large old-school disk drive and the latter is a modern emulator which is much smaller. I want an enclosure for the latter which looks like the original drive. I have already designed the pcb (although it will under go some changes) and have an original 1541-II drive from which I can take the necessary measurements and forward. The enclosure I want will be ~1/3 the size of the original (maybe smaller) and will not need to be a perfect clone, rather something similar. I am looking to use the model to have small number of enclosures manufactured, i.e. like maybe 100-250 for a first order (after I am satisfied with a prototype). It is preferable for the designer to be able to advise on how to go about manufacture, and also to own a 3d printer to be able to produce a cheap prototype (or two). I am based in the UK in Cumbria.
