From: TonyWaite on 20 Mar 2010 15:53 Hi Don, Using a diecast aluminium box slightly bigger than your project would be an easy way to go; get your nearest sheetmetal workshop to do the smart job you need for the slots and holes etc and then powder-coat it. I do these enclosures all the time; also some variants in sheet-metal, tig-welded at the seems; then the welding-fillet dressed smooth before powder coating. If there's an easier and cheaper solution,I haven't found it! Good luck, T o n y --------------------------------------- Posted through http://www.EmbeddedRelated.com

Nothing there that will address this particular need :< *But*, I think I have uses for at least two of their "stock" cases! (annoying that they don't have their entire catalog online for easy download!) Thanks! --don

For small prototype series, you can make a silicone mold from the 3D printed object and make some castings using far better plastics. Not too good on tolerances ofcourse, but a lot stronger than the 3D printed object. Maybe that is the process Dombo is referring too? Then there is also a direct method using a laser to melt a (nylon?) powder, not sure how tough that output is. -- Stef (remove caps, dashes and .invalid from e-mail address to reply by mail) This sentence no verb.

So far, I haven't concerned myself with easy/cheap -- except that I don;t want to go the route of a "production" design. In one case, I would actually *prefer* something that is very difficult to do "in quantity" as it adds to the perceived "value"/novelty of the device. Once tried to do a case with *glass* but mistakes are *really* hard to fix :-/

That's one to bookmark! Thanks, I'll see if they have a catalog I can browse off-line... |
