About this 3D model

This is a draft of our team's maze giveaway. We want to find a plastic cover for the mazes. The maze is designed to work with a 0.177" BB. Our team name and number is embossed on the back of the maze. I uploaded the ipt, igs, and stp files for the part. If anyone does modify it for their team could you let me know. My current thought on the plastic cover is either to buy some that I can glue to the maze - or pause the print in the middle after their is a spot for the cover and then continue printing with the idea that the material will print around the cover. I have not tried this yet - but will change the description if it works for me.
