This package contains two sets of .stls; those for FDM and those for Resin printing.
There are six parts to the FDM .stl print:
- the carriage and separate spade, which fits, hand grips up to the nubs at the end of the carriage box
- the wheels (2), which fit to the nubs of the gun carriage (the carriage axle nubs are meant to protrude 1 mm from the wheel hub)
- the barrel with rests on the half moons inside the trunnion, glue to desired elevation
- the gun shield, which has a fitting nub and is centred on the front of the carriage and trunnions
As always, print with full supports, at a fine setting (0.1 mm).
Carefully clean off the support material, particularly around the traverse hand wheels and gun sights.
If you aren’t sure, open the file in a CAD program and see what you need to leave and what conversely what is support material.
Always test fit before applying glue.
The resin .stls had two parts; the gun itself and the barrel, which can be secured at a range of elevation onto the half moons in the central trunnions.
The files are both the basic .stl and the pre-supported ones. It is you choice to use the pre-supported ones, as the angle of the part may not suit your tastes or printer settings. I tend to go heavy on supports.
