which case to print out?

[ljmerza]

i have a single 6 channel board and want to print out the case but its not clear which parts i need to print out

Through trial and error, I have discovered a couple of possibilities:

You can print 6channel_case.stl and 6channel_case_lid.stl. This is a fairly simple 2-piece snap-together case. When I printed it, the "tab" on the lid were slightly too big to fit the "slots" on the base (probably due to the nature of 3D printing). I'm trying to resolve that with minor scaling, but you can also just carefully trim the lid "tabs". There is also 6channel_meter_case.stl, which, as far as I can tell, is the same two pieces in a single STL.

Or, you can print the 3-piece case consisting of 6channel_energy_meter_2piece_case_main_board_large_half.stl, 6channel_energy_meter_2piece_case_main_board_small_half.stl, and 6channel_energy_meter_2piece_case_cover.stl. The small and large halves fit together but probably need some glue to hold them. The lid snaps in place.

I have had mixed results in printing these cases. That's probably mostly because I'm using a low-end Ender 3v2 printer. So far, I've been printing at 0.2mm layer height with a 0.4mm nozzle. I've printed them standing up and laying down, with supports where required.

If anyone has suggestions for improving prints for these particular cases, I'd love to hear them.
