Mount and process 40oz (and 30 oz) tumblers with a stepped taper profile with the eufyMake E1 rotary attachement. See timestamped video below.

The eufyMake E1 rotary attachment is a must have accessory for processing tumblers and round objects. It comes with a number of accessories but none that will assist with processing 40oz and 30oz tumblers with large handles and stepped taper profiles.

These tumblers present three potential problems:

1. The first is the size of the handle. Mounting the tumbler in the rotary attachment directly will likely result in the handle interfering with the rotary mechanism.
2. The second issue is with the tumbler profile itself. The stepped section at the lower portion of the tumbler causes the eufyMake E1 measuring system to tilt the tumbler drastically. The tumbler is now misaligned with the print head and will not work.
3. The length of some 40oz tumblers is slightly too long to fit in the rotary attachment.

However, by pressing one of these adapter rings onto the bottom it will solve all three issues. The ring will engage with the end stop slide and create a slightly shorter tumbler. It will also prevent the laser measuring system from tilting the tumbler, and it will also lift the tumbler enough to allow handles to rotate.

Three ring sizes are included as these tumblers may be slightly different from various manufacturers. It cannot be guaranteed that the rings will fit all 40oz / 30oz tumblers as there might be manufacturers producing sizes outside of these ranges. 

To get a sense of fitment, measure the bottom rim of your tumbler, if it falls between 73 - 75mm there is a good chance these rings will work for you.

Note that the part you receive will be bright yellow/green similar to the website brand color theme.
