Labeled socket organizer rail
Loose sockets in a drawer cost minutes on every job; a rail with sized posts keeps a 1/2 inch drive set in order and shows the size on each post. The rail is 300 x 40 x 10 mm with twelve square posts of 12.5 mm across the flats, 12 mm tall with small bumps for a light snap, 25 mm pitch, and engraved metric sizes on the base. Two screw holes let it mount inside a toolbox lid. Print it flat in PETG with 4 walls so the posts do not shear.
SpeakCAD sizes the posts and spacing to your drive size and the number of sockets in your set, and engraves the exact sizes you own. Switching to 3/8 inch or adding deep sockets is a single follow-up. Check the fit visually for free in the browser.
