I think that you could find some Patola box that satisfy the exactly dimensions of Axis Cam, you'll just need make the hole for lens!!
www.patola.com.br
Check for some model, call them and ask by some distributor in Vale do Paraíba or São Paulo, because you can't buy directly with Patola. They have MOQ (Minimum order quantity).
Let me know if you need anything more that I can help!
Abraços!!!
