This is a pegboard holder for my Bondhaus 6 piece hex screwdriver set. The piece fits in a standard ΒΌ" pegboard, and was modeled to fit the screwdrivers for this Bondhaus hex screwdriver set here: https://www.amazon.com/gp/product/B0006O4AD8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I'd recommend printing on its side for the best strength for the hooks (minor supports required). PLA should be fine.
