With the A1 being the bada** printer it is I find myself rarely needing many tools close by. As such, I took a more minimalist approach to a tool holder giving only a spot for the essentials filament Snips and the trusty scrapper.

Print this model flat with tree supports on however the hole for the scraper would be blocked and almost impossible to remove supports from so trust your printer to bridge that section. Be sure there is a support blocker in place covering the entire area. Other than that, this is a realtively easy model to print
