TupperWare lid

Although TupperWare has a life time guarantee, we found they no longer stocked lids for some of the older containers. Here is a solution to the problem.

Printed in TPU, I found it makes a nice flexible lid similar to the original. I print TPU at 220/110deg and 30mm/s.

I have included 4 lids of different sizes measured at the OD of the top of the container less a couple of mm for a tight seal. Other sizes can be made by modifying the circle diameter in the "lid size" sketch of this Onshape drawing.

To edit, make a copy of the workspace then change to suit your needs.
If you have trouble doing this, or you are not comfortable with Onshape, drop me a message with the OD of the top of the container and I will resize it for you.
