Great, compact Gridfinity Rugged box - 11U version was kindly provided by original author!

Find Rugged Gridfinity Box here as separate print profile!

11U is not the most common size because it is odd number, but for this project it was the smallest that could fit Whoopstor3 and Tiny Whoop and I didnt want to make it bigger by going to 12U.

This is first version and I am open for hearing ideas for changes or additions. :)

Consists of 3 parts:

A: 3x1x11U for VIFLY WhoopStor 3. WS3 fits tightly, plugs are accessible and ventilation holes open. WS3 can be used while in this insert. Prints on side with support.

B: Is bottom layer for battery. Height is 4U. In print profile there are multiple options. Empty boxes or boxes with dividers. Choose what fits you best or create your own based on this size.

• Batteries up to 77mm in length should fit.
• Width up to 7.5mm.
• Optional text to keep track of charged and discharged batteries, simply point the battery plug to correct side.

C: Insert for 75mm Tiny Whoop. In this case BETAFPV Meteor75. Holes to hold batteries for quick access.

Some sizes for making sure your whoop fill fit:

There are multiple versions in this print profile understand what you want and print it!

You could make this overall package smaller by not using Gridfinity, but for me this is great option, because I can use these inserts also in my Gridfinity compatible drawers for storage.

Enjoy!
