Mini re-entrant speaker

This is a re-entrant speaker just like any basic megaphone, where you can attach your own inputs and casing. No support is required.

Here's threads specs:

Tolerance: 0.15mm (Modeled female ends are already expanded by 0.15mm outwards.)

Output side

• ISO Metric Profile
• 25.0mm (M25 x 2, Class 6g)
• Right hand

Input side

• ISO Metric Profile
• 18.0mm (M18 x 1.5, Class 6H)
• Right hand

Other included models:

Attachments

• Simple hexagonal end
• Megablok attachment (3/2 height - You can use the half-height block to match with other full-height blocks)

Speaker These (along with spacer file) are specifically designed for the parts salvaged from this monaural earphone so that I can use the 3.5mm stereo mini jack as an input. This is just here for reference.
