Con lăn cuộn nhựa (1kg và 3kg)

This is the standalone roller unit from my Sovol SH02 3kg spool adapter.

If you plan to print directly from the Sovol dryer, use a heat-resistant filament like ABS or ASA.

Parts needed:

(4x) 608 bearings.

Instructions (it looks way more complicated than it actually is)

Note: Pictures are in order.

1. Print the parts. Random seams on the rollers.
    

2. Insert the half pins into the rollers, two half pins per side. The chamfered tip goes into the roller. They are tight but will go in. Push them against a table.
    

3. Insert the (4x) 608 bearings into the pins.
    

4. Drop those badass rollers into the frame.
