Need help with broken battery door

[KRDucky]

Hi guys,
So I bought an iJoy Captain X3 a couple of months ago now. The battery door no longer stays closed even without setting it down or knocking into it. I believe I am out of the 90 day warranty period and even if I am not, I no longer have the receipt.
As such, seeing as I have a friend who is willing to 3D print a new door for me, I need the 3D model files for the door. Preferably with any adjustments to improve said door. Does anyone have something?

I've the same issue with another mod and ended up putting a silicone case over it. Would that work for you?

A protective case for you mod, much like protective cases you can buy for your phone.
