Self made battery box

[Rhum-mar]

Hello,
To enhance the cost-effectiveness of the otoscope, I have developed a printable version of the battery box instead of the recommended purchase.

It maintains the original size of the recommended one, ensuring a perfect fit in the "Battery holder".

To further improve cost-effectiveness and reduce dependency on online material ordering, I have created two versions of electrical connections. One utilizes a self-made spring from any conducting metal wire, soldered to the wires. The other version uses parts purchased on Amazon for less than a dollar per set.

Thanks for the PR @Rhum-mar . We are working on a redesign to reduce the overall number of parts and I've brought this up with the team. I'll do my best to review this this month. At a glance it's looking good and I'll want to test how it integrates with the redesign.

Great work, @Rhum-mar . A couple of things to make this PR stronger:

1. Pull apart the two additions here:

• battery compartment
• alternate speculum holder

2. The file folders contain too much stuff. The source code (FCSTD) and print files (STL) can probably be together in a folder, but likely the photos belong elsewhere.

3. What is the speculum holder made in? It looks like it's a Step file? This can't go into the main tree unless it's FreeCAD or OpenSCAD.

4. I've been thinking about how best to offer the two speculum holders. Probably we should pick one default configuration to curate and make the other available as an alternate branch with a link via the README. I don't know, so open to the thoughts of others. From experience with previous devices, providing choice creates confusion and error unless it's done carefully and clearly.
