<p><strong>K-TAK RTE-1 (Ruggedized T-Beam Enclosure 1)</strong> is an open-sourced ruggedized tactical enclosure for the t beam m8n. RTE-1 is designed to help bring meshtastic to the roughest outdoor conditions in a small man-portable package. RTE-1 was designed around a large battery compartment ensuring space for a high-capacity battery; this will allow days of continuous operation on a single charge. It also utilizes commercially available waterproof components to offer a weatherproof and completely sealed body, protecting the electronics from the elements. Though not a beginner-friendly project, RTE-1 is relatively a simple construction. The body is 3D printed with CNC cutout "armor" panels for added protection and strength. However, the CNC parts are not necessary and can be substituted with printed parts. The CNC parts are relatively simple, with a drill press and good saw (and skill) it can be cut out by hand</p><p>Designed &amp; Developed under the K-TAC ecosystem by Canine Rocket Technologies</p><p>For full write up, CAD Files, and more check out the <a href="https://github.com/meshtastic/enclosures/tree/master/TTGO/T-Beam/M8N/K-TAC%20Rugged%20T-Beam%20Enclosure%201">GitHub</a> page.</p><p>For a visual profile of the project, check out the <a href="https://hackaday.io/project/184349-k-tac-rugged-t-beam-enclosure-1">Hackday</a> page.</p><p><strong>Trailer Video</strong></p><figure class="media"><oembed url="https://www.youtube.com/watch?v=_Ks4Oo0Oxe4"></oembed></figure><p><strong>Technical Overview</strong></p><figure class="media"><oembed url="https://www.youtube.com/watch?v=rQXneYTvGVU"></oembed></figure><p>&nbsp;</p><p><strong>3D Printing Info</strong></p><p>Included are 2 versions, one for FDM and one for SLA. The only difference is how the screws mount, for the FDM version the holes are larger to accommodate threaded heat-set inserts, whereas the SLA version has 3 mm holes intended to be tapped straight into the resin print itself. For the SLA version, all the files are identical except the center frame. Ensure you are printing the correct center frame file! For full rugged performance, FDM printing is favored over resin printing, however for more moderate usage resin prints should also work (Indoor, casual hiking, urban environment, ect.).</p><p>FDM Recommended Settings:</p><p>100% infill</p><p>0.2 mm layer height minimum</p><p>PETG, Polycarbonate, or ABS</p><p><strong>Tools</strong></p><p>3D Printer (The body is printed)</p><p>CNC Mill (See below if you do not own one)</p><p>Wire Snips</p><p>Soldering Iron (And basic soldering skills)</p><p>M3 Taps (Only needed for resin print version)</p><p><strong>Electronics</strong></p><p>1x TTGO T-BEAM M8N</p><p>1x OLED Display</p><p>2x 12 mm stainless steel waterproof push button (generic, make sure it's momentary)</p><p>1x Upgraded Antenna (stock antenna could work but not recommended)</p><p>1x 25mm GPS Antenna (stock antenna could work but not recommended)</p><p>2x Li Ion 21700 (Optional, other li ion cells pouch or even 18650s could work, but who dosen’t want to cram the biggest cell this enclosure will take right?) <a href="https://www.18650batterystore.com/collections/21700-batteries/products/samsung-50e">https://www.18650batterystore.com/collections/21700-batteries/products/samsung-50e</a></p><p>1x Set of male and female XT-30 Connectors (Optional, but these are our preferred battery connectors.
