NANO 500 for Small Printers V1

thingiverse

This design draws inspiration from https://www.thingiverse.com/thing:3289569, with similarities evident throughout the creation process. The hull has been refined to achieve a fairer/smooth appearance, while other components remain largely unchanged. Alterations to the hull necessitated updates to related parts, though rig components remained unaffected. To ensure optimal results, I have elected to initiate this new Thingiverse entry and revise all STL files accordingly. The Onshape design is accessible at: https://cad.onshape.com/documents/8b79235aec7f3796b70841ea/w/ebf9ec93dd759ed5e3378faf/e/36ea2b38b34cdddf9b3f9229. Users can navigate the design by right-clicking and using Alt to orbit, or Ctrl to pan. The original Onshape design will be deleted in due course. The Bow, Middle, and Stern components utilize single skins defined by their respective STL files. These parts require a well-set-up printer and customized slicer settings for optimal results. To achieve the best possible print quality, I recommend the following adjustments: - Allowing the nozzle to travel through holes to avoid obstruction - Elevating the temperature by approximately 10°C to 15°C to enhance layer adhesion - Increasing retraction amount and coasting amount to compensate for more fluid filament - Boosting flow rate by approximately 3% to improve layer adhesion - Enabling thin walls and checking slicer previews - Implementing z-hop on travels if necessary - Reducing speed - If all else fails, try using a different manufacturer's filament or type Most prints utilize a 0.2mm layer height, while smaller parts (or threaded components) use 0.1mm and non-critical elements employ 0.3mm. Three shells and 15% infill are used throughout. The design incorporates TPU parts, which require specific settings: extremely slow print speed, no retractions, significantly increased flow rate (+15%), and a 0.1mm layer height. Experience has shown that the top of the Stern print may distort slightly, but this can be corrected using heat from a domestic iron or similar. Some holes intended for M3 or M4 screws are oversized to allow them to form their own threads; however, tapping will still benefit results. MR105 bearings are used in goose-neck and pulley components. The foremost mast hole is designed for Swing Rig use, with six related STL files included. However, I do not intend to further develop the Swing Rig at this time. Note that 'Swing Rig Join X' requires bed supports. The design has undergone several updates: 8/6/2019 - Minor update to all hull-related files; 11/6/2019 - Stern updated; 14/6/2019 - Middle updated; 23/6/2019 - Keel size and weight reduced (approximately 5%) and moved back approximately 10mm for better waterline bulb achievement; 25/6/2019 - Bow, Stern, and keel stiffener updated to aid slicer performance; Servo Base updated; 28/6/2019 - Bow, Middle, and Stern printed with reasonably good results; 18/7/2019 - Servo Drum Center updated - 6mm diameter reduced to 5.5mm; 26/7/2019 - Servo Drum simplified - now 8mm diameter for increased turns on winch; 07/05/2020 - Original winch servo no longer available, and any standard size 2-turn winch should be suitable (e.g., https://www.ebay.co.uk/itm/Sail-Winch-Servo-1-5-6-Turns-5-12kg-High-Torque-Metal-Gear-for-RC-Boats-/323941848732).
