<p>Updates:<br/> 20/05/2020 - RC2: Added RC2 with 1mm Wall thickness for those using slicers gap-filling capabilities or nozzles that produce an extrusion width of &gt;0.5mm</p> <p>After printing over 300 and standing on the basis of the already great <a href="https://www.prusaprinters.org/prints/25857">Original Prusa Design</a> I redrew the part to optimise printing a little more.</p> <p>Firstly I reduced the wall thickness from 1mm down to 0.82mm as I found with my extruder nozzle of 0.35mm (extrusion width 0.42mm) I was seeing gaps between the two walls resulting in weakness, I've heard of other makers experiencing this issue too</p> <p>Secondly, to reduce retractions I removed the holes and replaced with a 'swoop', keeping the wall at a constant 0.82mm throughout this ensures that the print head completes the wall layer in a single pass with no returning to fill tiny microvoids which with PETG can lead to stringing and other artefacts</p> <p><img alt="Sliced" src="https://i.imgur.com/SszXhZa.png" width="500"/></p> <p>Finally, I removed the front-outward facing pips as I felt that added nothing to the design structurally, the newly printed part feels more robust perhaps you will have some success with it too!</p> <p>it also prints slightly faster I guess due to the optimized path and subtle geometry changes, only a small change but I'm printing 60 at a time and it adds up:</p> <p>Original Part: <a href="https://www.prusaprinters.org/prints/25857">Original Design</a></p> <p>Build time: 0 hours 15 minutes<br/> Filament length: 671.8 mm<br/> Plastic weight: 5.36 g (0.01 lb)<br/> Material cost: 0.09</p> <p>Optimized Part:</p> <p>Build time: 0 hours 14 minutes<br/> Filament length: 616.2 mm<br/> Plastic weight: 4.91 g (0.01 lb)<br/> Material cost: 0.08</p> <p>I have also included the STEP File should someone wish to make further modifications and augmentations.. all the best &amp; good luck folks!</p> <p>Pictured tested working with 0.5mm PP Sheild Plastic</p> <p>RC1: 0.82mm Walls - for printers with extrusion widths &lt;0.42mm<br/> RC2: 1.00mm Walls - for printers with extrusion widths &gt;0.42mm (or using gap-filling settings)</p> <h3>Print instructions</h3><p>Printed 0.3mm Layer Height<br/> 3 Walls<br/> 30% Infill<br/> Supports are not necessary.</p> <p>Ideally, print it from PETG.</p>
