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. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.
Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer? We print this part and ship it to your door. See its priceUpdated

Example prompt

Create a socket organizer rail 300 x 40 x 10 mm with twelve 12.5 mm square posts 12 mm tall on a 25 mm pitch, 0.3 mm retention bumps on two faces, engraved labels 10 to 24 mm in front of each post, and two 4.5 mm mounting holes.

This prompt comes with the ready-made model when you sign in, in case you want the AI to redesign it (3 credits a redesign); changing numbers in the viewer is free.

Fit notes

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 in the browser.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.

No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
