Tool to draw straight markings a.e. the waterpass on a model ship.

The files allow for a 3d printed version as well as a cnc made base. I used calibration weights for tires to make the base a bit more heavy.

For the 3d version you need to close the bottom with a 66mm platic circle after placing the weights.

I melted threaded inserts into the mount for fixing the position. If you choose to do so you should open the holes according to your inserts diameter. You also can thread screws directly into the plastic.
