I have such a beam rack, and also a bag that fits onto it (and a spare under-plate).
The spare is however too short for a new bag I would like to build. I wonder if anyone
has already made a 3d-model of the underplate that could be changed to be as long as needed
and then printed in a sufficiently strong material?
If now, how would I best go about measuring/digitizing the plate I have (what really is important is only th eunderside that must fit the MTX rails). 123d catch or such might be hard as the plate is black… any suggestions?
