Chainsword V2 remixed for more stability

Remix of Dxsus's great chainsword model.

Modifications: I modified the connection system with pins to allow a rod with 20 mm diameter to act as a core rod for the model, increasing stability.

Tested this with a typical 20 mm aluminum rod available at a hardware store for a few bucks, works great. Usually these tubes are sold in 1 m lengths, in full scale you need about 96 cm.

For my printer (Anycubic Chiron) the print settings that worked were 103% scaling for the body and 105% scaling for the pins that are still required.

You need to print:
- handle 1 and 2: once each
- blade: x4
- tip: once
- thin pin: once
- tick pins: x6
