Our parts are created from measuring or scanning the originals and are extremely precise although they might have some minor visual differences for example areas on the original that are hollow will generally be filled on the replacements, this is partly to make the design easier print but also makes them much stronger. The feedback we have had from all of our customers suggest that these replacement parts are actually stronger than the originals.
If the part you require isn't listed please contact us and ask about our reverse engineering service.
