prusaprinters

<p>For the railway fans: A clock in the style of the Swiss Railways Clock.</p><p>I've added a several railway company logo's to the dail. Other railway company logo's can be added on request.</p><ul><li>Blank, (no logo)</li><li>Nederlandse Spoorwegen (The Netherlands)</li><li>Deutsche Bundesbahn (West Germany)</li><li>Deutsche Bahn (Germany)</li><li>Deutsche Reichsbahn (DDR East Germany)</li><li>Deutsche Reichsbahn Gesellschaft (Germany untill end WW-II)</li><li>SBB CFF FSS (Switserland)</li><li>NMBS SNCB (Belgium)</li><li>Statens Järnvägar (Sweden)</li><li>SNCF (France)</li></ul><p>Just add a cheap clock mechanism (ebay, ali, etc...) (56 x 56 mm, 8.5 mm output shaft)</p><p>The dail diameter measures 295 mm. This is about the maximum size that fits on the bed of a Creality CR10.</p><p>The 1.2 mm (3 layers of 0.40 mm) thick dail is to be gleud to the 17 mm frame.</p><p>The logo's are 0.40 mm from the dail face, the minute markers 0.8 mm and the hour markers 1.2 mm.</p><p>By taking these numbers into account you can minimize/optimize the print time.</p><p>No supports are required.</p><p>A hole to hang the clock on a screw/nail is available.</p><p>Update 17FEB2019:</p><p>The seconds hand was not balanced and even when printed in HIPS too heavy. The clock movement does not have the power to move the hand between 6 and 12 o'clock.</p><p>By adding extra plastic is was not possible to shift the center of mass to coincide with the movement. Balance the seconds hand by glueing the required weigth of 3 mm rod/thread in the provided hole.</p><p>Update 23AUG2019:</p><p>Added the missing SBB/CFF/FSS clock dail.</p><p>Update 25AUG2019:</p><p>I realized most clocks are styled similar to the Swiss railway clock, but.....</p><p>the hands used in Switserland are unique.</p><p>Hour, minute and seconds hands for the SBB are added.</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>Yes</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>0.40 mm</p><p><strong>Infill:&nbsp;</strong></p><p>20%</p><p><strong>Filament:</strong> 12-3D PETG and/or HIPS White, Blue, Black, Red</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>&nbsp;</p><p>HIPS frequently needs to be printed with brim for proper bed adhesion.</p><p>How I Designed This ===================</p><p>Used a downloaded svg-file (source: wikipedia) in Fusion360.</p><p>&nbsp;</p>
