Testing my laser level with only 1 axis free to move.
It uses 2x laser line modules in a 3d-printed housing, with tiny bearings allowing it to pivot freely. The laser line module angles are adjusted with grub screws in the housing, and the centre of mass is adjusted (in both axes) by a pair of larger & heavier grub screws.
I probably want to soak the bearings in some solvent to get the oil out of them as they currently stick ever so slightly. Looks promising though.
Still to do:
- second axis
- battery power
- convenient mount with magnets and a tripod adapter

I got 2013th on the global leaderboard for part 2 which I am pleased with.
