I remixed thing:4558993 because it was the exact type of Testors paint rack I wanted only it did not offer any way to be mounted to a peg board which was what I really wanted. So I took the original file/STL and sliced it down in Fusion 360 to remove the original shelf bracket and added my own peg board mounting pegs to the back of it.

This turned out great and worked exactly as I had hoped! This should fit any Normal Style peg board with little issue.

You may have to use your flush cutters to trim the bottom corner of the peg board hooks to get them to fit your exact peg board. I use a 3d printed peg board from Thingyerse and I just had to trim the very corner off each peg at about a 45 degree angle which allowed it to easily slide into my plastic peg board. If you have a normal wooden peg board though you shouldn't have to do this.

Lastly I cut down the length of the original paint holder from 7 or 8 slots to 5 slots as I felt it was too long for most peoples needs on a peg board.. Now if you need more you can just print more mounts and keep stacking them on your peg board like I did in my photos.
