This models helps keep the Mr. Pen Professional Compass set compactly stored away. A great frustration of mine when using this kit is how bad it is to store, so this helps solve that problem with tremendous success.

To close, the model utilizes 10x5 n52 magnets, 3 in each the top and bottom for a total of 6. This is honestly a bit overkill as the case is extremely secure.

Finally, I included a section for a USB drive to fit into since I was utilizing it on a regular basis. If you wish to not have a slot for a USB drive, you can print the alternative plate without it. 

If you have any suggestions/comments/requests, let me know, and I will do my best to update you and the model in a timely manner.
