He added a knob to the wheel.\u003c\/p\u003e\u003cp\u003eHowever there were a few things I wanted to do differently. So I did.\u003c\/p\u003e\u003cp\u003eMy version is meant to be printed and attached three times. This means there is always one handle in an ideal position - regardless of the current base height of the machine.\u003c\/p\u003e\u003cp\u003eI also didn't want to increase the footprint of the machine, so my knobs had to be closer to the wheel.\u003c\/p\u003e\u003cp\u003ePer knob you need the following material:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003etwo 608Z skateboard bearings\u003c\/li\u003e\n\u003cli\u003eone M8x60mm screw\u003c\/li\u003e\n\u003cli\u003eone M8 nut\u003c\/li\u003e\n\u003cli\u003eone M8 washer\u003c\/li\u003e\n\u003cli\u003eone M5x35mm screw\u003c\/li\u003e\n\u003cli\u003eone M5 nut\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCheck the pictures on how to assemble the whole thing. The M8 screw will actually thread itself into the printed knob. The nut just helps with the initial start and provides the pressure on the assembly.
