Bricks sorting Tray for assembly & other things

Assembly station for obvious models and parts to assemble. Please be mindfull… This my first attempt at a 3d model design. I'm open to feedback and suggestions. This is a little revised version of what you see in the pictures (changed the connecting parts)I printed in to colors by switching filament manually, but single color as well as multicolor print profile is provided.You can print it without the center part and connect them with the connection blocks if you a smaller assembly station (see picture as example) I have designed this so you won't need any materials to use it, but there is chance I will make a new version were you can implement magnets for keeping the parts together. No support is needed, but it the overhang parts will come a little cleaner. Print profile is set to 90% of the size I printed, but feel free to print it at 100%, but be cautious for obvious things to be aware of:You need to manually remove the test print line that the printer prints at the beginnin
