puzzle box separator

I made this for a couple of Ravensburger puzzles my little one has that come with 4 puzzles in the same box. Why a company like Ravensburger didn't include some kind of separator is beyond me and is a bit frustrating when you just want to do ONE puzzle and get your kid to bed. So here is the solution. The nice thing is you can just adjust the size to whatever you need in the slicer and away you go. Print it at low res to print quick. I print mine at .25 layer height, .5 line width, 120mm / sec speed and PLA. Prints in under 2 hours. Measure your box first and make sure you subtract the thickness of the walls from the overall outer dimensions or you'll make a box where the lid doesn't fit on. Height is important so the pieces can't slide past it. Lastly, you may like to glue it down so I have made it with friendly wide bases under the cross to accept your favorite glue. Also keeps it stable and stuck while printing.

So basic, but I'm proud of it. Hope this saves some other parent's s
