Description
GDR's Carl Zeiss Jena used a special non-standard thread of M19x0.75 for their infinite tubus length objectives. This adapter allows to use it in modern M27 threaded microscopes.
Use PLA and a fine layer height of at least 0.1mm for proper threads.
Model files feature different adapter heights.
