prusaprinters

<p>This is my interpretation of a typical DDR "Bleichert RK3" crane in G-scale (1:22.5).</p><p>The HSB in Wernigerode (D), and other museum railways still uses them to load coal on their steam engines.</p><p>There is hardly any open source information to be found about these "East German" cranes.</p><p>I have based my model mainly on pictures from my my private collection and found on the internet. If you can provide detailed drawings, I will improve my model.</p><p>Manual operation of the winches for boom angle and raising the load is achieved by turning two "thumbwheels". They are mounted on a M4 thread, with a spring (i.e. ballpoint pen) in between for friction.</p><p>Construction:</p><ul><li>M2, M3 or M4 screw threads are provided for connecting items.</li><li>Hand rails: 1.75 mm filament or metal wire.</li><li>Operating levers. 1.75 mm filament.</li><li>Door hinges: ~1 mm metal wire</li><li>To correctly align the pulley on top of the boom, and the ladder to the main body, use some 1.75 mm filament.</li></ul><p>(Positive) feedback to improve this model is welcome.</p><p>Best regards,</p><p>Rob</p><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p><strong>Printer:&nbsp;</strong></p><p>CR-10</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>.15</p><p><strong>Infill:&nbsp;</strong></p><p>25%</p><p><strong>Filament:</strong> Extrudr GreenTEC / GreenTEC Pro-CARBON Black</p><p>&nbsp;</p>
