This is a replacement knob for an IKEA Tarva dresser. It will likely work as a handle in many other applications. Best used with wood screw sizes 5 or 6.

Why the weird batman-logo shaped screw hole?

• Of the several screw hole designs tried, this one provided the best balance between being easy to screw in by hand while feeling sturdy to pull on.

How is this knob better than the other designs on Thingiverse?

• Because it works. I tried printing several other knob designs but none of them worked: Either the hole was too big for my screw or there were fancy parts of the design that my printer could not handle. This design is simple and solves both those problems.
