Replacement parts for Silvercrest SKBA2A1 Bluetooth Headphones (circa 2017)
Designed due to broken plasic pieces while still being fully intact otherwise.
Inner piece fragile but functional due to forgotten strenghening rip.
Inner piece ca 1mm too short but functional
Pillars (Outer piece) and drill holes (inner piece) not 100% aligned but assembly is possible
With the printed parts the original screws where too short and had to be replaced with longer ones that somewhat fitted
 

printed a long time ago on an ender3 so print quality is not the greatest
