Functional battery boxes

I am still working on tolerances. It is really tricky to get things to fit together perfectly. I don't have so much as a spare millimetre in the battery box design.

This is a render of my shine through battery level lights concept. I have tested and bright LEDs easily show through the 0.3mm layer of PLA. I just don't know if it will still work once painted.

This is the light from my monitor shining through the PLA.

Its looking good,
Would it be feasible to paint that face with just a clear protection coat instead of a white paint that may block the light?

That's kind of what I was thinking - put a piece of tape or something over the lights before painting. Would have to make sure and print them in white but it can be done. Maybe a .5mm inset (or bump) around them just to make it easier to know where they are located during painting.

I tried a thick coat of primer filler and a coat of white paint over the 0.3mm PLA and the bright LEDs still show through. They are nowhere near as bright though, and the paint quality was still pretty bad. Needs more sanding and primer layers to get rid of the print texture.

I think whether it works or not will depend on how much current the Battery level board can supply to the LEDs.

I am happy I have a completed version of my battery design. Smile

Unfortunately, I accidentally left it at work over the weekend and don't have any photos of it. Sad

I am going to start work on the external battery box to suit. It is essentially Michael's design with the sides made thinner. I hope it works.

Still haven't ordered my 18650 cells, because I should really get my car back on the road first, so I am keeping my fingers crossed that I have left enough tolerances and the cells will actually fit into the battery I have designed.

I was printing individual parts for my battery box as per Michael's original design, and then realised I could save time and effort by printing the tube part as a single part.

Ok, first test of my almost complete battery box works surprisingly well. I still have to tweak some of the tolerances, but it slides in and ejects back out!

I have done a new design for a two piece battery box instead of the three piece (one of which isn't printed yet) design in the video above.
