Still not completely happy but this is big improvement.

I went back to my original design (http://www.thingiverse.com/thing:2537) and cut out everything that wasn't actually doing something.

Then I oriented the pieces so that nothing would press along the "layer" lines so hopefully this will be a stronger than my previous design.

I think result is cleaner, I know its smaller and will use less material, with any luck however it will prove more useful and durable.

As usual the SKP file is included for anyone who wants to enhance, adapt, improve, etc.

Updated (v4):
Overhang corrected
Battery end tabs merged
Battery end tabs moved to increase grip
Extra holes placed to ease contact positions


This design is untested.

1 STL = 2 parts - Either screw or glue in place.

stiff wire is pushed up through holes in the base and hooked over the springs to for the contacts.

Have you tried printing this flat? I would think you could it all as one piece no?

I made it ages ago when overhang was a much bigger problem... I plan on revisiting it sometime but I'd also be more than happy for someone to remix/improve it.

made one but didnt realize it was

Very kewl pic,

I think I must have miss selected as I normally put stuff up as noncommercial...
I've changed it now so feel free to use publish or improve, I figure it could probably do with being a fraction wider for starters :)

Any chance you could post the two pieces in separate stl files?

No problems, STLs attached.

Whoops, top tab is a nasty overhang...but it somehow managed to print anyway!
The top tab lost half of its width to sag, though. I wonder if it would have been better to just connect it (thinly?) to the bottom tab and either leave it connected, or fix it in cleanup...

I think I would have rather had the two parts as separate parts though, rather than on one platform.

The tabs on the cross piece probably need to be a bit taller to hold the batteries in firmly... maybe continue the curve they already have.

I think the two piece tab with overhang could easily be changed to a one piece tab touching both batteries, and I think it would be fine.

I think the side tabs are too weak to hold up a wire, assuming you pulled it through the hole in the bottom. I'd suggest another groove in the middle of the v
ertical edge (and if you join the tabs, a hole to match) to line up with the battery terminal... then you could pull the wire up from the hole in the bottom and then wrap it around the tab, both strengthening it and making a big contact.

This simple piece is pretty near perfect I think, just needs
a few minor tweaks! Very nice.

Awesome, I noticed the overhang problem after I posted it ( it had been a very long work day and I wasn't thinking right...)

I love your suggestions, I've got a couple of other designs I want to get down before the ideas fade but I should be able to make a new version tonight.

I don't think those two tabs on the top are printable without support material. You'll probably have to either rotate that part back to flat, or extend the tab on the bottom to meet the top.
