Better Tolerances on Reindeer Christmas Card

I really liked this design, but after printing it, I had to use a jewelers file on all the notches for them to fit & they were still quite tight. I created a sketch in fusion 360 with the base profile of this. Changed the notches from 1.4mm to 1.5mm. One of them was actually 1.0mm. With a Z height of 1.4mm, the .1mm tolerance worked perfect for me. I included a STL file & fusion 360 file.
