thingiverse
This is quick and easy design in TinkerCAD, as I need knobs for some M6 furniture bolts I have laying around. These bolts are round heads with 4mm allen key sockets (10-13 mm diameter heads).
There are two types of knobs and two different designs.
Type 1 is Glue in and type 2 is for use with a 10mm deep threaded insert. There are two different star patterns too.
