Motorised shades cog small

Cog wheel from zemismart blind motor which works with roller shdes that have beads with a small gap between them, the kit come with three cogs, small space, large space and rope cog so this is the first copy done which works with a 12v motor and Drzz motorised roller shades esphome sketch and a d1 mini.
the shaft of the motor is a tight fit so I widened the hole by 0.1mm .
held together with 3mm bolt and nut and might be good to put some super glue on the two dowels to lock them in place.
