QCY-H3 Hinge Repair Replacement Part

Suitable for repairing broken injection-molded right-side hinges on QCY H3 earphones. It's a direct replacement. ABS printing is recommended; do not modify slicing parameters. Performance testing is satisfactory; at least, it's less prone to breakage than the original part.

Due to the inability to precisely measure the internal groove shape of the original injection-molded part, the original damping effect cannot be replicated. Vertical damping will be lost, and the horizontal rotation limit of the earphones will not be entirely consistent (but it will be present). Consider using this as a compromise.

Of course, since only the right side broke for me, only the right-side model is available. I'll model the left side when it eventually breaks.

PS: This earphone has broken three times in my possession. I couldn't get a replacement through after-sales service this time, hence the creation of this model. It seems to be a design flaw in this product; there are many similar descriptions of breakage in the same area online, it appears to be a common issue. I've asked the Taobao customer service to inform their R&D department, and to pay attention to strength issues in future versions.

It is recommended to use a heated rod-shaped object to thoroughly clean the cable channel and hinge mounting hole after printing to facilitate subsequent installation.
