spell slot indicator

I saw a design very similar to this made of wood and became inspired so i designed this. the version I have made I made it piece by piece and I had to cut it into half to do so because of my printer bed size. i printed it with out the pegs or anything on it and then glued post printing the pieces that needed glued. I would love to see improvements made to my designs if one is made. For wizards and bards for sure you will need 22 rings for a max lvl of these class. you will also need nine of the pegs if you print the design with out pegs which i have not tried as of uploading this.
