Stop losing your hex bits with this storage rack. The hex drill set is from Harbor Freight and the right angle bit driver is another great tool from DeWalt. Print the holder upside down. It did lift up a bit at the edges during the print, making the bottom a bit like orange peel and the wings were a little off square but not really noticeable once on the wall. I also had to fettle a few of the hexes at the opening with a Swiss file, which is not surprising given these surfaces were in contact with the hot print bed. Fix to wall with 3 x E-Z Ancor dry wall anchors or similar. You may have to open the holes slightly for these - a function of printing them without support probably.
