This is a remix of flummer's battery box in order to use different battery contacts. The contacts I am using are available here for a quite reasonable price:

Overall the battery box is slightly more compact than the original one (about 2mm less in thinkness and 6mm less in length).

Printer Brand:



Prusa i3










It should print without issues on most printers and using most settings :-)


Adding the contacts

I use a tiny amount of hot glue to stick them in place.

All I've been getting for customizer on this file is "/usr/local/bin/openscad/openscad: error while loading shared libraries: libCGAL.so.10: cannot open shared object file: No such file or directory " :-/

Great design, it will be very useful for many of my projects.
Oredered 2 packs of the clips from Banggood.
Thanks for sharing

i like it just missing something to close like a box...

I would like to see this same custom battery holder for Li-ion18650.

so use the customizer or openscad

its not very parameterised, but i guess search'n'replace 55 => 65, 15 => 18.

not sure what the 5, 4.5, 8, 1.5, 7 etc. are

Sorry, I did not see the openscad file..... Thank You

i just made this test remix which should hopefully fit my protected 18650's which are about 69.3mm long and 18.3mm wide


printing it now, the springs haven't arrived in the post yet though

18650 + PCB battery box

Thank You, saving me some work. Already downloaded.. I am also waiting for the springs...

I found that the one I remixed fits my soshine lifepo4 and panasonic/sanyo NCR18650A li-ions which are about 69mm long

i've made a new remix for my samsung icr18650-26f which are about 65 long, which i hope will also fit my unprotected GTL's which are about 67m long. the new remix i've made much more parameterised and tidied so should be easier to edit. i've also removed the +/- from the underside which didn't even print for me, and made the channel from the solder tab connect to the wires.

printing now, will upload in a mo.

I really like idea, that I can go to this website and print custom battery holder. Thank you!
