3D printed with stainless steel bars. Plastic color varies.
This version (TALL) is for Numark PT01USB turntables manufactured in 2014 or newer (see the bottom of your PT01), and the PT01 Scratch (2016).
One order includes 2 sets of platter bars (4 steel bars, 2 pieces of plastic).
See the platter bar install guide.
These bars greatly reduce platter wobble under your scratch hand.
Note that these bars are designed to not touch the platter during normal playback. However, the platter will rub on the bars when the platter is pressed down, while scratching. This rubbing is audible. Adding oil to the bars can reduce this noise.
