The three sections are held together using M2 18mm machine screws.</p><p>To power the badge, I used a 1000mAh LiPo battery which fits neatly inside the case. Note that Tufty 2040 has no charging circuit, so batteries / cells need to be charged externally.</p><p>The badge was printed using Overture Neon Green silk PLA on an Ender 2 Pro.&nbsp;</p><p>I printed using the following settings</p><pre><code class="language-plaintext">bed_temperature = 60 bottom_fill_pattern = monotonic top_fill_pattern = concentric bottom_solid_layers = 5 fan_speed = 100 0.16 quality 0.4 nozzle infill = 25% first_layer = 210 Celsius other_layers = 205 Celsius travel_speed = 100 perimeter_speed = 40 solid_infill_speed = 40 top_solid_infill_speed = 30 first_layer_speed = 20 infill_speed = 40</code></pre>
