3D model description
The model of a material handler in HO scale (1:87), inspired by a Sennebogen 850E from the 2000s.
This model was designed with FDM printing in mind but you might have better results with an SLA printer. If printed on an FDM printer, you will need a 0.25mm nozzle (or finer) and layer heights of 0.05mm.
I modeled all of the joints and then exported different positions of the moving parts. You will have to choose a position of the boom, arm and cab as well as decide to either print the open or closed grapple and the extended or retracted leggs. (I have provided multiple angles for each joint but I can provide other positions / angles if needed)
I had to simplify some parts of the model, mostly the hoses (I only modeled half the number actually present on the real machine, one per cylinder instead of 2).
The model uses an M4 x 10 (or x12) bolt to secure the upper body to the base and the turntable.
The boom, arm and cab use 1mm or 1.8mm pins on all of the joints. the other joints are directly printed in the correct postion (for the leggs and the grapple)
