Pika,
I believe the schematic Valkyrie has given us for the box is as follows:
Top and Bottom of the box: 14 1/2" W x 7 1/4" H or vice versa depending to your design
Side 1 & 3: 7 1/4" W x 5" H or vice versa depending to your design
Side 2 & 4: 14 1/2" W x 5" H or vice versa depending to your design
I'm gonna re-design to match the specifications, so I should have something in the next few days.
I can make you a bumpersticker if you like, it won't be coated or anything but I can make it and send it to you if you like. I can do a t-shirt but it won't be anything special, just a transfer iron-oned to a tee.
PM me and I'll send you a bumpersticker and if you want I can see what I can do about a t-shirt.
Matthias
