Brompton carrier stretch hook

prusaprinters

<p>The original broke - let's reproduce!<br/> The original has no possibility to insert the (2 tied) strech bands so I added a slot. It's very tight but when you stretch the bands while pressing it through the slot it goes through pretty well.<br/> Printed without support, hot with PETG, 5 perimeters and 30% infill for hight stress resistence - seems working as good as original. However, I just made it - no real life test yet..</p> <h3>Print instructions</h3><h3>Category: Parts Print Settings</h3> <p><strong>Rafts:</strong> Doesn't Matter</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> egal</p> <p><strong>Infill:</strong> many perimeters is more important</p> <p><strong>Filament:</strong> read text below PETG<br/> <strong>Notes:</strong></p> <p>the print settings thingiverse asks for are partly strange to me. The Amazon link is generated automatically and has NOT my agreement and leads to totaly wrong product! I mislead it by design. Brand I recommend is 'dasFilament' they sell in germany/eu but not at amazon. Color doesn't matter respectively it's your choice..<br/> Pretty often number of perimeters are at least as important as infill, in this case even more. This one got 5.<br/> I print PETG with 248ºC nozzle temperatur because this works best for stable tools and high layer adhesion.</p> <h3> How I Designed This</h3> <p>it's a fast, almost dirty construction this time.<br/> I sketched it in ZY (shaft) and XY (hook), then I used a mix of foto (1.5m distance) and measurments to ensure the original dimenstions.</p> <p>Extruded, extended the shaft (no honest reason actually), in "Patch" mode I extruded a Spline into a 'paper', thickened and positioned it afterwards back in 'Model' mode. (see picture below)</p> <p>Dirty but handy last step was to cut the shaft on one site so it becomes easy printable.</p> <p>As allways I add the f3d file</p> <p><strong>slot cut</strong></p> <p><strong>reference: large distance as possible to get more 'orthographic' view</strong></p> <p><strong>Slic3r ready-to-print view</strong></p>
