This model is a knurled knob designed for use with an M6 nut. It is ideal for adjusting the X-axis belt tension in upgraded Prusa i3/P3Steel printer parts.

Construction Features:

Combines elements from two designs: a parametric knurled nut knob and a thumbscrew with the Open Hardware logo.
Includes OpenSCAD source files for further customization.

Printing Recommendations:

Print with PLA, 30% infill, 0.2 mm layer height, and 0.6 mm walls and top/bottom layers.
Can be printed in either orientation, but optimal results are achieved when rotated 180 degrees with the logo facing up.
Heat the M6 nut with a soldering iron before embedding it in the knob's nut trap.
