Many thanks to SWLing Post<\/em> contributor, Eric McFadden (WD8RIF)<\/a>, who asks:<\/p>\n

Thomas, what’s the orange thing on the MTR-3B in the last photo in your post about the Red Oxx Booty Boss?<\/a> [see photo above]<\/p><\/blockquote>\n

Glad you asked, Eric! It’s a 3D-printed protective cover.<\/p>\n

My daughters have been asking for a 3D printer since they’ve used them at Maker Faires, the Pisgah Astronomical Research Institute<\/a>, and most recently the Huntsville Hamfest<\/a>. Both of my girls love designing and creating things, so this year we got them one for their birthday.<\/p>\n

After loads of research, I purchased a Creality Ender 3 Pro 3D from Amazon.com (affiliate link<\/em>)<\/a> for about $240 US. My daughters were thrilled when they unwrapped the box on their birthday to find a 3D printer inside! We spent the following morning assembling it, calibrating the print bed, and printing a sample file.<\/p>\n

Like most, our first prints were fun, simple things we found on Thingiverse<\/a>.\u00a0 The girls printed a Saturn V rocket, a cat, and an X-Wing fighter. Those prints gave us an opportunity to learn about slicing 3D files, building support structure, and proper bed calibration.<\/p>\n

Covering the MTR-3B<\/h1>\n

When the printer arrived, I already had the Red Oxx Booty Boss<\/a> on order and was assembling my field radio kit.<\/p>\n

\"\"<\/a><\/p>\n

One concern I had about the MTR-3B (in any pack) was that the small band switches could catch on a zipper or pocket mesh and be damaged. I had read a few accounts of this happening to others.<\/p>\n

\"\"<\/a>

The LnR Precision MTR-3B transceiver<\/p><\/div>\n

I thought about keeping the MTR-3B in a thick poly bag, but I knew that wouldn’t offer a lot of protection for the switches. Out of curiosity, I searched Thingiverse hoping perhaps someone had designed a small case that could possibly house the MTR-3B.<\/p>\n

To my surprise, I discovered an engineer actually designed a snap-on cover for the MTR series of radios<\/a>. It was then a simple matter of downloading the file, slicing it, and setting it to print while I slept that night.<\/p>\n

The next morning, I had a cover sitting on the printer bed.<\/p>\n

\"\"<\/a><\/p>\n

I purchased a pack of multi-color PLA filament knowing it would give my girls an opportunity to play with color a bit. The printer was already loaded with bright orange filament which I thought would be brilliant for the MTR-3B.<\/p>\n

\"\"<\/a><\/p>\n

Those of you familiar with 3D printing are probably aware that ABS would be a better, stronger material for the cover since the side clips are certainly the weak points of the structure. We haven’t ordered ABS filament yet, but I think the PLA will actually function well for a while–it’s sturdier than I anticipated. When we have ABS in the house, I’ll plan to re-print it.<\/p>\n

\"\"<\/a><\/p>\n

I couldn’t be more pleased because the cover fits the MTR-3B like a glove and doesn’t add a lot of bulk to this pocket-size transceiver. It was also a great print for beginners.<\/p>\n

\"\"<\/a><\/p>\n

And best of all, I know the front switches and buttons are well-protected in my field bag.<\/p>\n

\"\"<\/a><\/p>\n

I’d like to thank Thingiverse designer CockpitBob<\/a> for designing this little cover and sharing it!<\/p>\n

We’re also super pleased with the Creality Ender 3 Pro 3D printer<\/a>. Thanks to my friends who helped guide that purchase decision.<\/p>\n

Care to share?<\/h1>\n

3D printers are incredibly useful tools for radio enthusiasts of all stripes. I’m still very<\/em> new to this world, so I would love to hear about your 3D-printed radio projects. Besides this post, we’ve featured at least\u00a0one in the past<\/a>, but I’d love to share more.<\/p>\n

Please comment<\/a> or contact me<\/a> if you’d like us to feature your 3D project!<\/p>\n
