I printed in petg and pctg 0.3
The author remixed this model.
Anatomic grip for better handling, variations for both the back shapes, the press 23 one is the round one, wind knob on the right. The othe one is for the version 2 with wind lever on the right.
Super if combined with the wonderful #Ligero69 camera.
