A 3D Printed Case for the DIY Outernet Kit

Thanks to Manuel (aka Tysonpower) for writing in and sharing his 3D printed ‘Universal Outernet Case’. Outernet is a satellite file casting service that uses an RTL-SDR based solution for reception. With an Outernet set up you can receive things like daily news, weather updates, books, Wikipedia pages and more all for free. About 20 MB of data can be transmitted in one day.

The DIY Outernet kit consists of an RTL-SDR ‘SDRx’ board, patch antenna and C.H.I.P single board computer. The patch antenna needs to point roughly in the direction of the Inmarsat/Alphsat satellite in your area. This can be a problem because the Outernet patch antenna doesn’t come with a stand or mounting solution.

Manuel solved this problem with his 3D printed Outernet enclosure. The enclosure houses the patch antenna, SDRx and C.H.I.P, and also doubles as a stand for pointing the patch antenna. Inside he’s also fitted a small 30mm fan to keep everything cool while inside the enclosure as the C.H.I.P is known to have overheating problems.

Over on YouTube Manuel has uploaded a video explaining how the enclosure is made with 3D printing, demonstrates the assembly steps and finally shows the final product. The video is narrated in German, but it has English subtitles available. The design files required for 3D printing the case are also available on thingiverse.

A 3D Printed Stand for Generic MCX RTL-SDR Dongles

Thanks to Jaime (EB5ABT) for submitting his 3D printed stand for the generic MCX RTL-SDR dongles. The stand is designed to hold one of the generic dongles on it’s side so that a small whip antenna can be attached to it, whilst staying stably upright.

If you’re interested in printing the stand for yourself Jaime has uploaded the design files to his dropbox. He has also created a short YouTube video showing a slideshow of his stand which is shown at the end of this post.

If you’re interested in 3D printing accessories and enclosures for the RTL-SDR then thingiverse.com has a range of user submitted designs, ranging from custom RTL-SDR dongle enclosures, to stratux Raspberry Pi + dongle enclosures, to Outernet patch antenna stands.
