Simple 4in square tray divided into 4 compartments.
By request, I've added a 1x1 and a 1x2 version. They don't exactly stack they way I'd like, but there they are.
By request, I've added two new configurations. I've also thinned the wall to 0.8mm and re-uploaded all of the parts. This builds really well on a Replicator 2x in ABS.
Prints without a raft or support, however helper dots have proven very helpful to keep the corners down. Standard build height of 0.2mm works well.
