Prusa MK3 max build size reference

Because it's hard to see how close you're getting to the edge of your max build size when designing something. I made a reference block of the max build size for the MK3.
(xyz): 250 x 210 x 200 mm
(Obviously you can grab the STL and edit it for your printer if you have a different one)

So for example, if you're using 3D Builder from Microsoft. You can import this STL and compare it to the model you're working on. And that away you can see how close you are to the edges.

(If you use 3D Builder, and switch X-Ray on as seen in the pic. Then select the item you are testing, you can see how well it fits inside the build area)
