3d-printing a thinner HP41CX back cover
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, |

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. --Bob Prosperi |

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! |
