Mark,
Call me Michael, I have not designed or printed anything other that these two, mainly because I have not had the need for anything else. I would be glad to try to help with other enclosure boxes. All I would need are some detailed pictures and some general dimensions of the original enclosures. As Walter mentioned, these 3D printed boxes are not very sturdy as printed. However, after the components are installed and they are potted, then they are perfect for the job. All the enclosure must do is hold the components and the potting materials until the latter sets up. I have 2 of the 465/475 HV multipliers running as well as the 455 model. Some of the other HV multipliers are more complex, but I would be willing to try to help with designing the STL or 3D models. I am not in this as a commercial business, just a dedicated hobbyist. I have printed some of these for others, not charging for the 3D print. All I ask is that they cover postage and, in the case of the 465/475 enclosure, the cost of the new mounting hardware. Please let me know if I may be of any assistance.
Sincerely,
