This is a 1:16 model for 45 mm track
It is based on my drawings for a standard German 600 mm, 1 cbm Muldenkipper according to DIN5963 (https://www.printables.com/model/281716-muldenkipper-lorry-din5963-no-brake-for-45-mm-trac)
Axles: standard LGB axles running in MR63ZZ bearings (3.0x6.5x2.5 mm)
The bearing holders are fixed to the frame with M2 screws.
Use some wire to simulate gas-tubes and get creative to mak a model blow-torch.
The author marked this model as their own original creation.
