The orange fuse for the HV battery is stuck how can I get it out?

I’ve removed the plug many times and each time it got increasingly difficult. But this time it just absolutely refuses to come off. I tried WD. The handle came off. I tried using pliers and ripped the cover off so now the inside is exposed.

I just want to say how terrible this design is.

 

I finally got this bitch out but now I’ve missed my swim session goddamnit. I guess now I have to make a lid for the exposed part. What do you guys think is safe?

 

I reattached the handle, glued a piece of cardboard over it and with the WD properly lubricated it does come out properly. I think I’ll leave it at that D:
