Power of the Primes Volcanicus Backpack for Slash

I thought that Slash needed a way to combine with the rest of the team. This will allow her to attach to the back of Volcanicus as power pack of sorts. The final version of the design contains multiple 5mm ports to hold the individual dinobot's weapons when in combined mode. This attachment is three files. All three will print without need for supports of any kind.

I have included both the completed backpack and the backpack blank for those who would like to create their own versions of the pack. If you make a new design please let me know. I would love to see it.

Instructions
Print One copy of each piece.
Glue the Back Plate and Slash plate together flat to flat with your favorite superglue.
Cut the two pegs apart and insert them into the top holes on the slash pack. They are a tight fit so glue shouldn't be needed.
Some slight trimming might be needed depending on the accuracy of your printer.
