This is a remix of the previously uploaded tray inserts for wider fasteners or a larger number of fasteners.

I generally manage the text layer in Fusion and export from there, but I have included some placeholder text for editing in the slicer.

For colouring I generally pick a base colour, slice and then select a layer about 41.4mm. Right clicking on the slider on the RHS and selecting change filament allows for robust repeatable colouring with a minimal of filament changes.
