Replacement drawer pulls for IKEA furniture line called HEMNES.

The original knobs are die cast metal and feature a gloriously sharp edge, which might be fine for most applications, but their HEMNES bed line has the pulls about 6 inches/150 mm from the floor, which is great for digging into the top of your bare foot.

This design utilizes an incorporated M4 nut (McMaster PN: 90591A255) and requires a longer M4 screw (I used 30 mm long McMaster PN 92005A232). However, depending on how thick the drawer face is, you may need to adjust the length of the machine screw you use. The depth of the nut in the knob and the maximum depth of the hole in the knob mean that you need to pick a screw that's between .59" and .92" longer (15 mm and 23 mm longer) that the thickness of the drawer face you're attaching these knobs to.

The pre-sliced profiles have pre-programmed pauses at the time when you have to drop in the nuts to continue to the build. One profile has a 5 mm brim in case you're having build stability issues, but mine built without it.

The black knob in the picture was built at .35 mm layer height, but the blue knob is the print profile layer height of .16 mm.
