About this 3D model
These ARE small, the same dimentions as IKEAS own knobs for the particular book case in the title. SO: Due to popular demand, I have added a extra large version, that still uses the same 4mm fastener. Its about 50% larger than the “normal” versions. look in profiles to find the extra large version. Added a V2 that has chamfers on the inside, as another profile pointed out that could help with burrs from the holes and similar, I wanted to spruce up my bookcase doors with some nicer doorknobs, so I whipped up two different versions in Fusion. Screws in easily and grabs the scew well. I would recomend to print these with atleast 4 walls, so make sure the inside walls are sturdy enough for the screw to bite into, Printed at 0.1mm with 25% infill. Check out my other models here
