I have changed the License for the Caliburn from Creative-Commons Non-Commercial to Public Domain. The hobby at large now owns the design and anyone that wants to either develop and sell derivative designs, or sell assembled/kit blasters in parallel with me can do so.
This is the same timeline and license I did with Plusbows because I knew I would never personally be able to produce enough of them for them to make a difference in the hobby. I am producing infinitely more Caliburns than I ever did Plusbows, but there are International sales that I think could more efficiently (and more cheaply) be offered domestically in places such as United Kingdom, Australia, Singapore, and Taiwan than would be feasible for me to produce and export to those customers over the next year.
So if anyone in those countries is reading this and would like to sell these over there in my stead I'm fine with that. You can localize the hardware used or produce them identically to how I am now. Not everyone is willing to pay $65 in shipping beyond the sale price to get one of these and I understand that.
The largest quantity of anything Nerf-related that I ever produced was Longshot foregrips. I made 150 of those over 3 years. Given the current rate of production I expect to surpass that number with Caliburn-related items before Christmas. I'm on the 40th blaster (kit or assembled) and have put together over 50 hardware sets.
