Here are the dimensions and a pictures of someone that made one for an MP40, 4x4x6 3/8 with one side of the box with a 5/8" extension.
I not sure how much smaller the dry side of an MP10 is compared to an MP40, but those dimensions fit fix in the same tank.
I guess what I'm looking for is someone with experience with acrylic or even a good reference for someone in the area that does acrylic.
Any input is greatly apprecated!
