IKEA Hemnes drawer knob replacement with M4 screw
A replacement knob for IKEA Hemnes and Malm drawers that reproduces the round 25 mm shape when one cracks or goes missing from a second-hand dresser. The knob is 25 mm in diameter and 22 mm tall with a 12 mm neck, and a captive M4 nut pocket 7 mm across and 3.2 mm deep so a standard M4 machine screw from the inside of the drawer front pulls it tight. The top is domed with a 2 mm fillet and a matte finish prints best face down on a textured bed. Use 4 walls and 40 percent infill so the neck does not shear under daily use.

Example prompt
Design a round drawer knob 25 mm in diameter and 22 mm tall with a 12 mm diameter neck 8 mm long, a domed top with a 2 mm fillet and a hexagonal pocket 7 mm across and 3.2 mm deep for a captive M4 nut, matching an IKEA Hemnes dresser knob, with a 4.5 mm through hole.
Fit notes
Knob diameters, neck heights and screw threads vary between IKEA lines and years, so a knob generated to match the surviving ones looks right rather than obviously replaced. In SpeakCAD you give the diameter and screw size, preview the knob in the browser, adjust the dome in the chat and download the STL.

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.
