Using the plans here: spacemodels.nuxit.net/lunokhod/lunokhod.htm for a 1:10 scale model of the Russian lunar rover Lunokhod 2, I've created an STL version of the simpler Lunkhod 1 (basically adding all the extra sensors and cameras would drive me completely round the bend).
It's probably the ultimate cyberpunk machine with the appearance of a robotic toilet on wheels.
I've obviously left out a lot of small detail and made a lot of the thinner parts oversize with a minimum print size of 1.2 mm diameter, which has allowed me to print out the bits at 1:20 scale with a minimum diameter/thickness of 0.6mm. I've mostly limited things to 0.8mm unless they are well supported and used 1mm square for many trusses that should really be only about 0.5mm round.
I just need to fit the spectrometer to the front then try and print out the four low-gain antennae, which will be a challenge as they are 35mm long and mostly only 0.8mm diameter.
I'm accepting the shortcomings of 3D print, rather than adding non-3D printed parts, as it want to explore both the capabilities and limitations of the technique.
Unfortunately it's a bit fragile. Shame I haven't got a bigger printer, it would be impressive and more robust at 1:10!
Photos of the model, unpainted, to follow.
