open source 1u blockered 5x3 artisan holder made in about under an hour
big jingesque cuts on the sides, round front lip, smooth chamfers into both. also has my username on the bottom and a heart i put on my stuff sometimes
6.3 deg, 9 mm ffh, 9.714 mm afh without feet. holes are 20x20 mm so this should be able to fit any 1u i think
you also need bumpons which you can get on amazon us or mcmaster or wherever else you can get 8 mm bumpons
