An adapter to allow the use of 7*9V batteries to replace a #467 B battery in old equipment.
Should be pretty close to spec sizes, depending on your printer and shrinkage, etc.
Why is this needed?
I recently acquired an 1950's era device that requires a #467 battery. This style of battery was also common in many tube and radio applications.
Replacements that I could find were upwards of $60, however I found this document https://www.scribd.com/doc/129382115/Replica-Eveready-467-B-Battery which described an approach for making an adapter to hold seven standard 9V batteries in the original space confines. I adapted the model and made a few design modifications. It works! A tight fit, and should probably still be wrapped in electrical tape to keep things from moving.

Notes:
If you can print long bridges support is not necessary. I used Cura with Enable Bridge Settings and other modifications to make the bridge supports pretty easy to remove.
I would consider this to be somewhat of a work-in-progress in that modifications may need to be made depending on the type of connectors you choose, etc.Wiring up the batteries
If you print with supports, which is probably a good idea unless you can long bridges pretty well, then they should be removed.
Following the design inspiration of https://www.scribd.com/doc/129382115/Replica-Eveready-467-B-Battery the batteries are wired in series. The original design used some nice connectors, apparently, but I just cut apart some very cheap generic 9V connectors, cut in half, and then soldered together. Do whatever works for you. Wiring diagram reference pic attached.
Also, while it will stay together without tape, I would recommend just taping around the perimeter for a little bit of extra security in terms of keeping the batteries in.
From cardboard to printing
As mentioned above, this is based on 2012 design that used cardboard. This was initially modelled in TinkerCad because they have a nice 9V battery model. Then moved to Fusion360.
This is actually version 2, which cleaned up the design a bit and added a better through-hole for the wiring. It should work fine as-is but if you have any fitment issues
