Nắp che bụi/plug cổng DC 5521

I created a port cover to protect my solar generator's DC output ports because it didn't come with any covers. Quick and simple design but effective. This is meant to be printed using flexible filament. I used Filatech FilaFlex40 and the default prusa profile.

Update:1/26/26 - Someone noted that these aren't long enough to fit on some devices. They fit very snug on my Ecoflow battery, however it was simple enough to extend them real quick so I've uploaded some with an 11mm barrel length which should be the standard plug size. The original one is still available with an 8mm barrel length. Hopefully this will work for more devices.
