This is the portfolio's existing verified shared public forwarding alias. It forwards to the owner and is reused across tools; no new Ellipsepin mailbox has been created. Your email provider and the forwarding service process your message.

For a calculation report

Please include the full major and minor diameters, the selected unit, whether a total end allowance was entered, and the output you expected. The downloaded text report can make the exact inputs clear. Do not include confidential drawings, private addresses or personal information that is not needed.

The calculator itself does not upload measurements. Sending them by email is your choice. This address is for website feedback, not a promise of workshop design, fabrication advice or a particular response time.
