Braun ET 66 battery compartment cover

This battery compartment cover is printed to order in black ASA. It is intended to replace a lost cover, which leaves the button cells exposed. It is the cover only – not the calculator or batteries.

What you get

• One replacement battery compartment cover in black ASA.
• Cover only: the calculator and batteries are not included.

Intended for

The design is based on a cover made for the Braun ET 66 pocket calculator; the designer reports testing it on an ET 66. We have not yet confirmed the fit on an ET 66 ourselves.

Check the fit

The designer notes that the cover's clip needs fine print settings, and we are still confirming that it works as intended on our printed covers. Compare your calculator's battery compartment before ordering. If you are unsure, contact us with clear photos of the back of the calculator and the battery compartment, so we can help identify what you need.

Material & finish

Printed to order in our workshop in Great Dunmow, Essex, in black ASA, a heat- and UV-resistant material. Fine layer lines are a normal part of the 3D-printed finish.

Made to order

Each cover is printed after you order. See the delivery section for the current dispatch estimate and postage options.
