Amazing project! I have adjusted some parts. Those in 1,5 mm pin and frame to 2 mm diameter, as I have found only 2 mm and 3 mm pins. I have also adjusted all moving parts, to give more tolerance, 2,6 and 3,6 mm, for better fitting in pins, with filament type and PLA and bed temperature that I have used. I have also re-designed escapement spring. I am now in the process of adjusting weight for better accuracy, but it works correctly!!
Thanks for your design
