Zepter/Banquet Baking Tray Lid Replacement Clip – Snap-Fit Repair

Zepter/Banquet Baking Tray Lid – Replacement Snap-Fit Clip A 3D-printable replacement for the plastic retaining clip used on a Zepter baking tray lid. The original clip has two small snap-fit locking tabs that can break during removal or installation. Rather than replacing an otherwise perfectly usable lid, I decided to design and print a replacement. Designed in Autodesk Fusion. Design The replacement follows the general shape of the original clip, including: - Asymmetric U-shaped profile

- Two snap-fit locking tabs at opposite ends

- Matching retaining hooks

- Rounded edges for more comfortable handling

- Reinforced locking tabs with a smoother transition into the main body

The goal was to preserve compatibility with the original lid while making the fragile parts a little more durable. Dimensions Approximate overall dimensions: - Length: 68.64 mm

- Maximum profile height: 25 mm

- Shorter side height: 11.2 mm

- Profile depth: 17.92 mm

- Wall thickness: approximately 3 mm

Please check the dimensions against your original clip before printing. Recommended print settings - Printer: Original Prusa MINI+

- Material: PETG

- Layer height: 0.15 mm

- Print orientation: Flat base on the build plate, U-profile facing upward

- Supports: I used forced supports under the locking pins, but maybe they are not even necessary

PETG is recommended over PLA because the locking tabs need some flexibility. Testing and development Version 2 – Reinforced design The revised model includes: - Stronger locking tabs with reinforced transitions

- Rounded external edges

- Improved geometry intended to reduce stress concentrations

Installation - Check that the printed clip matches the original dimensions.

- Align both locking tabs with their corresponding openings in the lid.

- Carefully press the clip into position.

- Avoid bending the locking tabs excessively or forcing the part into place.

- Check that both tabs engage properly.

Important notes - Do not use PLA or PETG near a hot baking tray, inside an oven, or in conditions exceeding the filament's temperature limits.

- The locking tabs are small and should be handled carefully during installation.

If you print this part or adapt it for another Zepter lid, feel free to share your results! Happy printing! 🛠
