Not explicitly for the TJ, but inspired by vacuuming it out. Needed a brushroll/beater bar to get dog hair out of my TJ's carpet, as the shop vacuum attachments weren't cutting it. Found that the SEBO vacuum turbo attachment is extremely powerful with the airflow provided by a shop vacuum. But, given the SEBO vacuum is German, it uses 36mm hose fittings, and the Ridgid shop vacuum uses 2-1/2". And I couldn't readily find an adapter for that. So I drew one up and printed it in solid polycarbonate in about an hour. Likewise, you could just as easily print an air intake adapter or anything else this way.
