Qidi 3D X-Max - Filament Spool Holder Lock

My rails of Qidi X-MAX filament spool holders wasn't strong enough to hold my attached filaments. During removal of back cover and rails as part of “silent upgrade mod” broken parts was found. I created this spare part to replace the broken parts.

Printed with PLA (ABS is recommended) with supports, 20% infill and 0.15mm layer height.
