I created this bead tray for a jeweler and it came out very well with the first iteration, now I've created a 2mm high ridge all the way around it and increased the depth a little for the grooves.

Notes:
-There's a possibility of warping at the edges of this print so you have to account for that
-I recommend printing at 100% infill for that extra weighty-ness. Although 30% is still fairly solid
-Requires gluing if you don't have a crazy big build plate (sorry)
-Was designed to fit on a flashforge creator build plate (a makerbot replicator clone) but I have also uploaded a one part version if you have a huge build plate
-Watch out for warping and it sticking to the build plate since the bottom layer is a large surface area
-Approximate dimensions as a whole: 42cm (16.5") x 5cm (2")
