Axle for M416 trailer using 1150 bearings

A different design for the axle of ossums great trailer https://www.thingiverse.com/thing:2055193:
- uses 2x1150 ballbearing (D11/5x4mm) like in most Tamiya-Kits used
- uses M5 rod length approx. 160mm (like the original, length depending on the wheels you choose!)
- uses simplified (yet with less free-play!) brackets and shackles and M3 screws (brackets are now same for front and rear) so you print 4xbrackets and 4xshackles and need 6 screws M3x16, 6 M3 lock nuts and 12 M3 washers.
