The internet is a remarkable source for all manner of things. This includes an almost dazzling supply of 3D printable files for all different types of tanks, guns, terrain pieces etc. in any scale you fancy!
I started modestly with a search in Thingiverse that revealed a collection of 1/200th AFVs created by Marco Bergman, and shared most generously, free of charge to anyone who wants to use them privately. (https://www.thingiverse.com/thing:232248)
I decided to start with the US M1A1 so downloaded the .stl file and converted it to .gcode in Cura.
The file as downloaded had the hull and turret stood on end, gun and bow facing upwards. This is probably a sensible way to go as many printers (mine included) have quite limited print bed sizes. However for reasons known only to myself, I decided to lay both parts flat and print them side by side. The picture below shows how that progressed.
- The print started with creating a "raft" to support the finished parts. This helps to ensure good adherence to the bed (but doesn't guarantee it!)
- The supporting ribs for the underside of the turret are starting to appear here. These are easily re,moved afterwards.
- Another view of the turret building up layer by layer
- The almost completed turret has now appeared
- The settings used on my printer, showing the 1.75 hour build time!
