hi, I made my own version of Watch Maker Trays.
They are specially designed for mechanical automatic watches like the ETA 2824-2 but can be used universally.
I have adapted the individual areas to the assemblies. For example, the balance wheel is individually separate from the escapement group because of the sensitive hairspring,
The small parts of the mainspring group are in their own area and each area has space for the screws for better order.
In one of the areas there is an indentation for the winding shaft so that the automatic movements do not twist and become annoying.
I recommend printing it with organic supports.
The author marked this model as their own original creation.
