Modular carriage & nozzle plugs for prusa i3

This is a modular carriage to host a 40x40 nozzle fan and a 51x51x15 blower fan to cool PLA.

It carries "plugs" designed to securely host jheads without requiring much mechanical work and calibration at each change.
Electrical connection modularity will be next step.

I designed plugs for j-head bowden, j-head direct drive, Immaginaecrea.it hotend in bowden mode (it originally mounts a 60mmx15x15 alluminium profile for cooling).

Among the advantages I see:

• good nozzle cold end cooling
• the blower mount and duct (if you choose e good blower you're fine, avoid low cost ones... but befare of noise of good ones!)
• the very low profile (allow to max print height to 190)
• the mount to x carriage which is standard 50mm spacing with 2xM3 screws.

You'll need:

• 2x M4x20 screws and 2 M4 nuts, for the plug locker
• 2x M3x40 screws and 2 M3 nuts, to mount it to the carriage
• 4x M3x20 screws and 4 M4 nuts, to mount the fans.
