This is a remix of "https://www.printables.com/it/model/547500-prusa-mk4-tool-holder" by SixtyFourWarrior and "https://www.printables.com/it/model/744017-mk3mk4-tool-holder" by steve457, I added a 38mm scraper slot on the back of this tool holder to make it more complete.
I suggest to print it upside-down to avoid too many supports.
