3d-printing a thinner HP41CX back cover - atilla457 - 02-26-2018 04:52 PM Hi there, I enjoy my 41cx, but sometimes wish it was a little bit thinner. I think there are a couple of people on the forum who are skilled at 3d printed parts. So is it possible to redesign the back cover and make 41cx a little bit thinner? thanks, RE: 3d-printing a thinner HP41CX back cover - rprosperi - 02-26-2018 05:57 PM (02-26-2018 04:52 PM)atilla457 Wrote: Hi there, While feasible to make the lower portion a small amount thinner (perhaps 1-2mm as it sits just above the CPU board), the thickness of the upper portion cannot be reduced because of the ports for the 4 x ROM/RAM modules. And since that cannot be reduced, very little would be gained by reducing just the lower section. So a lot of work for very little benefit IMHO.

Unless you make it a real half-nut with 2 module ports RE: 3d-printing a thinner HP41CX back cover - hth - 02-26-2018 07:29 PM (02-26-2018 07:02 PM)Didier Lachieze Wrote:(02-26-2018 05:57 PM)rprosperi Wrote: the thickness of the upper portion cannot be reduced because of the ports for the 4 x ROM/RAM modules. I am so eternally grateful they did not implement that plan.

No ports and a Lipo battery. We could get rid of the mid-piece bezel and bottom on a half nut. Direct power onto the main board and get rid of the battery flex circuit... I just checked my boneyard and have about a half-dozen full nuts in various states of repair but no half nuts. Shopping we go!
