CA-87_Ion_Blaster remix

I remixed a few files. For easy printing I added the bolt, the chambers and the connector together. It can now be printed standing up. I advice to print the connector with a larger infill, 50% at least, so it can carry the can. The bolt+chamber+connector is not perfect, it misses 1 greebly, but I printed this myself and it looks good enough.

I also added the bolt handle parts together. This can be printed with supports. And I separated the greeblies in different files.

I scaled CA-87_Ion_Blaster_Cannon_greebly1 in Cura to be 3mm thick, the current version is too thin to print properly. Use a rim for this one

I also printed the magazine a bit shorter, by moving it 3cm down on the z-axis. I forgot to remix that file.

The end result uses a wooden stock, all the other parts are from this file.
