Marble Track Remixed Sample Tile

This is an attempt at stabilizing the marble track designed by ahmetcemturan.
I sliced a piece out of each bottom corner and translated that piece to the top corner. I have not printed it yet to test.
Also, as I lack any previous experience at all, I am not sure how to guarantee an identical shape and orientation cut from each corner.
I plan to print 2 and test their stackability and rotatability. If it works well, I'll try to repeat for the other block styles. If somebody with more skills and experience wants to take this idea and apply it themselves, that would be great, too.
EDIT: I made a few more to test the uniformity of my corner cuts. The 2 blocks I printed fit together pretty well, but it's clear that the cuts I am making do not match exactly.
