Speaker spring clip

Wharfedale loudpanels had a broken spring clip so I designed a replacement.
The idea is to fit into the cavity with a m3 screw to provide leverage instead of the original spring (which was lost).
This was printed in PLA 0.05mm layer height with a 2mm brim. 50% infill. When installed with the nut and bolt the clip will pinch the speaker cable and provide contact to the speaker. Presumably this would work for other speakers with the same or similar type of connector (size accordingly).

I've added a second file with an additional piece that could be glued on top for extra support although the screw isn't supposed to be tightened too much.
