Colecovision cartridge shell 3d models?

[omf]

does anyone have any 3d models of a colecovision cartridge shell they wouldnt mind uploading.

 

the end goal of mine is to 3d print a couple off to house a few of the available games that have been posted for download.  they would need to be in an editable format like inventor or step because they would neeed to be modded a little to accept the non standard circuit boards i posess
