I just picked up a CPS 3000 from my cousin's house, and when I received(sp?) it, I found that it had no backpack with it. Does anybody have an idea on what I could do to make a replacement backpack?
I'm thinking along the lines of a PVC/ABS backpack, but does anyone have any ideas, apart from that, to make a backpack?
I think that your best choice in this situation would be a trashbag backpack (I don't know how to make it though) which is soft and looks like a normal backpack. Since I don't know how to make these though, you will need to find someone else's help.
Otherwise if you don't mind the bulkiness then a PVC backpack should work fine, you can always put it inside a normal backpack.
I got some suggestions from SSCF, for my replacement backpack, as they were saying things like this reply frrom joannaardway:

You'll need to find a way to attach this to your 3000 -(it fits well in a 3200, but the hose/gun connection is different to a 3000) - it may be easy.
 However, if you find no easy way - you can improvise as such:
 By cutting the pipe work back and filing it smooth - you can cut the connector down, and you can superglue the two faces together well. You might experience problems here - the "male" connector I used was "longer" than it needed to be, so there was spare space for the casing in between the "male" and "female" parts.

Your connection from the back pack should be one of these ^. |
I like the idea, and have even might consider something like the process above
