Abyss Diana Bass Ported Pad Adapter

Adapter to convert the regular Abyss Diana earpads (V2, TC, MR, DZ) to the bass ported ones.

Just place them between the headphone and the original earpads and enjoy the extra bass. The magnets are still strong enough to hold the earpads in place. 

The bass opening should have roughly the same surface area (mm²) as the original ones even though the dimensions & design is different. 

There are two versions available:

stable bottom: the bottom is 0.5mm thick (0.3+0.2 layer). Total height 1.45mm
slim bottom: the bottom is 0.3mm thick. Total height 1.25mm

Due to given height limitations (height of the screws) you can choose if you want a more stable adapter or more stable earpad fit. 

Tolerances are tight. Make sure to have a well tuned first layer and set the first layer height to 0.3mm.
