Rollers for the microwave dish.

The inner diameter of the ring is 154 mm. The maximum diameter on the outer edge of the rollers is 182 mm, taking into account the chamfer on the rollers - 180 mm. The rollers are wider than usual - 7.5 mm.

Usually 3 narrow rollers are used, which causes a lot of pressure on the enamel, which is covered with the bottom and it is quickly erased. So I decided to reduce the pressure by increasing the number of rollers and their width. PETG plastic. I don't know how it will behave over time, it has a softening temperature of 70 degrees. You can print more rollers (attached a file), or, for example, cover them with varnish ... we'll see there.
