This is a first attempt at a model of the South African G5 towed gun/howitzer. It is based on a Sketchup library file by Xavi-arg, again using the SketchUp / 3D builder / Cura development route. Had to modify the files, as usual, and to split them up to be able to print them sensibly at 1:76 scale. The gun is split longitudinally to obtain a reasonable finish, otherwise one side appears very rough and difficult to clean (see photos of attempts). Used 0.05mm layers for the gun to try to get a better finish; some improvement. Note that a couple of pieces above the barrel might fall off on cleaning and will need to be glued back on... The base is not very detailed, and I might try to add a bit in the near future. Travel clamps are not yet modelled, as they were not in the original model.
Hope to assemble later this week.
Comments or advice welcome, as I am learning slowly, but having fun!

Filament: AnyCubic PLA Black
Notes:
Some bits around the gun are tricky to print... Rest seems fine. Gun needed a bit of filler when stuck together - my clumsiness in cleaning it; I took off some layers in places. Photo shows gun after filling but before filing. Adhesion of the layers of PLA is not brilliant - anyone any advice? Running at 195C with bed at 60C (both nominal).
Need to add a hole in the chassis and a matching projecting rod in the gun to permit rotation; will have to glue this first version together in a fixed orientation (but it is in travelling configuration, so this is not unrealistic).
Handwheels are a pain; decided not to remove supports in this first print. Still not quite right.
Print both gun halves with the joining face on the printer base, not as shown. Wheels flat with inside face to print bed.
