Custom Blasters for TR Hot Rod

After watching the Potp cartoon I wanted to do a custom Rodimus Cron and I decided to try my hand at making some show accurate blasters for him.  Now I'm gonna say this now because assuming this is successful I'm sure someone will ask this but I don't know if this will work for the Potp Rodimus Prime/Unicronus because I don't own either figure so I can't test them or get the measurements to make a version for them.  This is my first 3D model that I've made to try and recreate something from a show and unfortunatly its not 100% screen accurate but for some reason I can't open the file to edit it and I didn't feel like rebuilding from scratch.  If I had the time and could still open the file I would continue to work on it but I also have college stuff to do so maybe sometime in the future I will sit down and try to make one that is almost 100% screen accurate or find a way to swap out the arms and make an entirely new arm but for now this is what I've made.  Now I think the price is a little bit higher than I wanted it to be but I can't really lower it by that much at least I haven't found a way to yet so sorry.
