<h3>AtreuSLB50Plus / AtreuSLB50+ rev1</h3><p>Finally I had the time to wrap up my little side project started about three months ago, and I thought to share it here. Although inspired by the Atreus, I couldn't quite find the right compromise among the non-split ergo keyboards, so I decided to make my own.</p><h4>Features:</h4><ul><li>1x RP2040 (KMK on Raspberry Pi Pico), USB-C port</li><li>50x switches</li><li>1x SSD1306 128x64px 0.96in IIC OLED display</li><li>2x EC11 rotary encoders</li><li>1x EVQWGD001 rotary encoder</li><li>1x Pimoroni IIC trackball breakout</li><li>1x Active buzzer</li><li>2x micro switches (bootsel, reset)</li><li>3D printed case (5-10° tilt), plate, pcb</li></ul><p>I am slowly finalising the firmware configuration and I will eventually put it on github as usual. Wiring diagram and keyboard layout will come along later.</p><p>Name is lame, might change it later. That's all for now.</p><p>Reddit reference thread: <a href="https://www.reddit.com/r/ErgoMechKeyboards/comments/w3jflv/my_first_custom_keyboard_atreuslb50_is_completed/">AtreuSLB50+</a></p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p><strong>Printer:</strong></p><p>Ender 3</p><p><strong>Rafts:</strong></p><p>Doesn't Matter</p><p><strong>Supports:</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.2</p><p><strong>Infill:</strong></p><p>15</p><p><strong>Filament:</strong>PLA<br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>If printed in the recommended orientation, supports are only needed for the bottom plate.<br>Feel free to print in the orientation that best suits the quality results of your printer.</p><h3>Post-Printing</h3><p>M3 hex bolts and inserts are needed to put the case together.</p><p>I also melted the two bottom halves together with a soldering iron.</p><h3>How I Designed This</h3><p>The design started from a semi-automated customised process by forking an OpenSCAD hotswap pcb generator repository, subsequently heavily worked on Blender. I had also added cutouts for per-key rgb, but in the end I gave up the idea of hand wiring the LEDs. At least in this version which, for me, has been an insightful experience.</p><h3>Some Photographs</h3><p><img src="https://cdn.thingiverse.com/assets/c7/66/1e/8b/c2/e56d2f8d-51ef-4e49-99d9-09ec70a22736.png"></p><p><img src="https://cdn.thingiverse.com/assets/d8/96/0e/4b/a9/f24ff679-9c07-4fb5-bd56-5dec31ca9f4a.png"></p><p><img src="https://cdn.thingiverse.com/assets/51/a1/7c/e0/57/5c7b7823-352e-4dfd-9c66-9abcebc8d799.png"></p><p><img src="https://cdn.thingiverse.com/assets/c3/50/40/1b/25/b9ba6810-9314-4a36-bd20-b60cd568fc61.png"></p><p><img src="https://cdn.thingiverse.com/assets/65/27/e9/e6/b9/1907563f-22fb-40ef-9e0a-e11c40321e31.png"></p><p><img src="https://cdn.thingiverse.com/assets/a0/86/2a/52/8c/fbe69b24-d7b2-4e21-8024-efbd855db3a4.png"></p><p><img src="https://cdn.thingiverse.com/assets/25/c1/a9/15/54/f19934e3-68e2-46ef-8f4b-986e7aa0b788.png"></p><p><img src="https://cdn.thingiverse.com/assets/0a/1b/bb/a8/78/e3025753-e275-4087-bce7-c0a4788fa423.png"></p><p><img src="https://cdn.thingiverse.com/assets/4a/03/98/be/e1/c3b6d116-aa10-40dd-92a2-2cc1e5171727.png"></p><p><img src="https://cdn.thingiverse.com/assets/d5/7e/21/96/cd/543a61a1-87cd-4cf0-b168-7b0a3938619d.png"></p><p><img src="https://cdn.thingiverse.com/assets/e4/e4/03/3f/bf/4e82a816-8a10-4e55-bf5b-3e80cdc4f66e.png"></p><p><img src="https://cdn.thingiverse.com/assets/bb/04/09/53/89/063048c8-b1cb-4f8f-a924-87d58577037c.png"></p><p><img src="https://cdn.thingiverse.com/assets/0e/52/c9/c8/f9/483f896a-f955-4c7d-9af5-fcbce5886905.png"></p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Computer</p>
