After receiving some good suggestions on my single Extension Cord Cover design ( https://makerworld.com/en/models/1058050#profileId-1045833 ) I decided to design a Large Multi Extension Cord Cover! 

This cover is a great option for anyone connecting multiple devices/ cables to a single multi-connector extension cord. Could be useful for many applications including outdoor lighting, outdoor christmas and Halloween decorations, supplying electricity to different equipment in a dusty workshop and many more! 

This cover was printed using PETG-HF. The print comes with different bushing sizes to fit different extension cord cable diameters ranging from 8mm to 16mm in 2mm increments (if you have a specific diameter cable that doesn't quite fit these bushing sizes just let me know and I'll upload the new size). The print also comes with blank bushings to plug the ports that aren't in use. The cover is water, dust and snow resistant. If you wanted to make it waterproof, I'd recommend applying Silicone to the sealing lip and the bushings.

The cover is print in place for easy assembly. I'd recommend measuring the cables you're looking to cover and simply printing the bushing sizes you need. Selecting the right bushing size will not only provide a better seal but also provide proper cable strain relief.

Can be used with different multi-connector extension cord designs including the following (in-line vs strip style). As mentioned above, simply use blank bushings to plug the ports that you aren't planning to use.

**Important note for the print: This is a large flat print design. If you have an open air printer (like me and my A1) make sure that you thoroughly clean your print plate and have a good first layer adhesion to avoid “curling” at the edges.

If you like the print, don't forget to rate, comment and boost!

Enjoy!

Update [2025-02-19]: Added new print profile to accommodate extra large connectors.
