Problem: as I get older, its harder to grab on and manipulate those tiny 1x1 bricks. I also like to have them near perfectly aligned. Solution: a tool that can hold the brick and allow your to manipulate it precisely. Took a few designs to get it right.
Self explanatory, used PLA 20% fill. Sorry its in STEP format, for some reason shap3r would not export it in stl.
