LDA 15' Phase Plug - Screw Cap

This is for implementing a phase plug on the [La Dolce Audio 15' open baffle mid-range driver](https://www.ladolceaudio.com/la-dolce-audio-bass-midbass-open-baffle-coaxial-woofer-coming-soon/). This screws into the back of the driver where the 1' compression tweeter would normally go. This is for users who have moved the tweeter to a separate horn. This closes off the hole and can be used with any of the LDA 15' Phase Plug designs below:
- [Standard](https://www.thingiverse.com/thing:6594247)
- [Cone](https://www.thingiverse.com/thing:6594251)

If you don't have a 3D printer, you can get any of these components printed by a 3rd party like [Craft Cloud](https://craftcloud3d.com/).
