If you can spare about $30 t0 $40 then you can easily build it yourself.
Someone was already gracious enough to design Axel's weapon already digitally on the Pepakura gallery. All you need to do is get the pepakura program, upload the design, then print it out on card stock. The rest is just cut and paste to put it together. Then finally you'll use fiberglass resin to harden it.
In case you have doubts you can easily look up any other Pepakura project to see how they turned out which I might say came out really good.
Well I hope this helped.
When in doubt, just take the next small step.
With that next step take a deep breath. It calms the mind.
When the mind is calm you realize the best is still yet to come.
