IKEA Besta cable pass-through grommet for a 60 mm hole
A two-part grommet that finishes a hole drilled through the back or shelf of an IKEA Besta TV bench so HDMI and power cables pass through cleanly without chewed melamine showing. It fits a 60 mm hole cut with a standard Forstner or hole saw, with a flange 70 mm in diameter and 2 mm thick, a sleeve 59.5 mm across for a 0.25 mm fit, and a snap cap with a 25 mm cable slot that closes the opening. Six 1 mm ribs on the sleeve grip the 18 mm panel. Print both parts flange down in PETG with 1.6 mm walls; no glue is needed.

Example prompt
Design a two-part cable grommet for a 60 mm hole in an 18 mm IKEA Besta panel: a sleeve 59.5 mm outer diameter and 20 mm long with six 1 mm grip ribs and a 70 mm flange 2 mm thick, plus a snap-in cap with a 25 mm wide cable slot, 1.6 mm walls throughout.
Fit notes
Besta backs and shelves differ in thickness from Kallax or Malm panels, and hole saw sizes vary, so a grommet generated to your panel and hole fits first time. In SpeakCAD you give the hole diameter and panel thickness, preview the grommet in the browser, add a brush insert in the chat and download the STL.

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.
