Use the modellers paint rack to organise your 3D printed parts (into colours, weathering techniques or the model the part is going on) before you start painting.
Keep things organised:
As you paint the 3D printed parts, move them from one rack to another for drying. This way, if you’re doing multiple coats, you know where you are up to and you can start again without overloading the painted surface causing a run
before you paint, use the rack as a holding rack to glue the 3D printed part to a bamboo skewer to make handling and painting easier
Assembly:
Just pop the modellers paint rack out of the holding frame and glue the part with the small square holes into the top slots of the side panels.
The one with the large square holes in the middle slots and the one with the two rectangle spaces (remove the rectangle spacers first) in the bottom slots.
Put the rectangle spacers on top of the middle panel in positioning into the tabs spaces to hold in place.
Glue the two mount frames (the bottom two panels) together, lining up the laser lines so they have a step at both ends
