I’ve made a few enclosures now and I’d commission myself to help you, but the problem with a custom enclosure like this is that even given the dimensions, you need the deck you’re working with to build your mold on so that it fits like a glove in the end. The enclosure needs to fit the specific amount of concave on the deck. Seriously, try making it DIY, i learned with @iamasalmon dope guide
It is the alot of work but nothing like having an enclosure that seriously fits your deck so so perfectly
