Hex-Key Knob for Hex-Head Nut / Bowden Filament-Tensioner Bolt
thingiverse
Got a Bowden? ------------------- Got a Filament Tensioner Bolt that's a Hex Head Bolt? ------------------- Got any Hex Head Bolt that needs a knob on it? ------------------- Yeah... me too. I couldn't turn my Chinese-clone Bowden's tensioner bolt by hand, and never had an Allen key, hex-key, to hand for it so I designed and printed a hex key on the base of a knob to turn it by hand. The default is a hex key end that is 3mm AF and 3mm high, as was my requirement, and the knob is 12mm high (inc hex)... but the Fusion360 file is provided so you can customize it as per your requirements via parametric design. Enjoy.
