Magnetometer board holder

An insert in a 1.5" sch 40 PVC tube to hold a HamSci PSWS magnetometer board. Designed in OpenSCAD so it is inherently parameterized.
A board is inserted in the holder and the holder inserted in the pipe which is capped and placed in the ground.
The holder has a slot for the board and tabs that fit in notches in the pipe for positive location. I made the notches with a file.
