LX200-OnStep Conversion - Dec Block Bracket

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 are two small holes which needs to be tapped; one at M2x0.4, and the other M3x0.5, as found on the drawing. They take M2 and M3 screws respectively.
