I setup every year a Christmas village with lights. I decided this year to try and make the storage and movement of these models easier by putting them all on little trays. This is the tray for the ice-skating rink.
Simple - not much of a lip just to prevent the lego model from slipping around while moving. Something I noticed needed work on the larger models. I also removed the inner edge fillet on the larger models, so there is a square corner inside. This one is filleted on the inner bottom face and that makes grabbing parts easy, but also allows the model to slide out.
The author marked this model as their own original creation.
