### Context:
This is part of a project to convert a Meade LX200GPS to the OnStep system. The project is documented in "Conversion of LX200GPS to OnStepX", by Richard Francis, 30 April 2025, available in the Files section of [email protected].
### Fabrication:
3D printing is possible but the the result is rather flexible. What's more, if the OnStep drive parameters are mis-set the stepper motor can become hot and this jhas a tendency to permanently distort the plastic part. So 3D printing in plastic should be considered more of a test fit or proof-of-concept than as a permanent solution.
CNC manufacturing in aluminium is preferable.
Note that there is a small holes which needs to be tapped, at M2x0.4, as found on the drawing. It takes an M2 screw.
