Hello Sir,
Note: I am new to Freelancer but I have worked on 3 Projects with Standard's like IP 67 waterproofing.
By the time you accept, within 2 days I'll be giving you 6-7 design variants you can have a choice. Once you are okay, we can have an hour conference video call to get to know about all the parts which is going inside.
By now I can able to design an enclosure for your Product.
To mention, We have in-house 3-D printing technology. I can also Courier you the 3D printed parts to you sir.
Regards,
Vrishabh Awati
