The metal feet are stronger than the plastic feet, making the machine more stable when engraving.Easy Sliding Adjustment: SCULPFUN roller adjusts the

size of the space between the two shafts by sliding, and fixes them by hand-twisting the knob, which is easier and faster than the traditional multi-stage fixing hole adjustment.100% Original High-Precision Engraving: SCULPFUN roller uses a high-friction 70A rubber shaft to prevent slippage, and the linear speed of the rotating surface has been precisely calculated.
