These are simple spacers which fit the plastic clips on the soundcore q20 and create a flat mating surface for traditional ear cup replacements like those for the beats studio.  Print one reversed to fit each side.

This model is a set of headphones made using drivers harvested from broken beats solos.  The driver housings are the correct size for replacement beats solo ear cups.  I installed the speakers into the housings and the back covers onto the housings using hot glue.  Be careful not to block the cut in the driver housing with hot glue as it will create too much pressure on the speaker membrane when the ear cups seal against your head.  The strap simply snaps in place.  I used a set of cheap earbuds to connect to the drivers.  The strap should be printed in something like PETG for flexibility. 

UPDATE:
The headphone strap must be printed such that the layers go front to back on the model rather than vertically otherwise they are likely to separate as the strap flexes.  To avoid the same problem on the sections of the strap that hold the ear cup I divided the model such that both sections of fragile geometry can be printed separately and in their optimal orientation and then attached together using adhesive.

Just a quick print to fix one of the most classic problems with this device.  You probably wont need supports.  I printed this at a resolution of .28 with PETG and it came out functional.  Good luck.

Keep in mind 3d printed threads are not always accurate.  These threads are 14mm negative but run small so print with multiple walls and in a less brittle material.

Bar mounted shifter based on https://www.thingiverse.com/thing:112602 but modified for use with wide range/mtb derailleurs.  It has about 1.4 times the pull ratio of a normal shifter.  The lever has been made longer to compensate.  It is also reversed like a shifter for a front derailleur but this is because it is intended to be mounted on the bottom of a right bar.

Non-printed parts:
2x #10 Nylon Lock Nuts
2x #10 x 1" Machine Screws
1x #10 Washers
1x 1-1/4" fender washer
2x 1-1/4' rubber washers
Splicing tape (or thin piece of rubber) for mounting (standard electrical tape does not work)
