Pull Handle

<p>My girlfriend needed a pair of handles, on a rope, for her physical therapy after her shoulder replacement surgery. &nbsp;I went looking for a pull handle and after spending 2 hours trying to get the model to print nicely, I designed my own.<br><br>This should work for many of your pull handle needs. &nbsp;Broken handle on your Lawnmower, snow blower, leaf blower, etc.? &nbsp;Try this handle. &nbsp;Need a pull handle for your attic access door? &nbsp;Try this handle. &nbsp;Need a new handle for your door? &nbsp;This handle might not be for you…<br><br>The model is currently configured for a 7mm rope diameter; however, you can change the diameter in the Fusion360 model and generate a new 3mf file for printing. &nbsp;Or tie a larger knot in the rope.<br><br><strong>Print Notes</strong><br><br>This handle should be printed in the orientation shown in the model, i,e, bottom down. &nbsp;I turn on supports, set the style to “Snug” and check “Support on Build Plate Only.” &nbsp;This provides some minor support for the inside of the handle where the hole steps down in diameter, it will probably print fine without, you do you :)&nbsp;</p><p>Printing with a 0.4mm nozzle at .2mm layer height, the curve of the handle feels very nice against your fingers. &nbsp;I've also printed the handle using variable layer height. &nbsp;Start where the sides of the handle transition from vertical walls to a curve, and I set the layer height to .07mm. &nbsp;Return to normal height for printing the neck of the handle, and again step down the layer height to have a curve on the tip of the handle. &nbsp;This isn't necessary, but it does make the handle feel very very nice.<br><br>Using a .4mm nozzle, layer height a 0.2mm with no other modifications, print time is 1H44M<br><br>Using a .4mm nozzle, layer height at 0.2mm with variable layer height as listed above is: 2H46M<br><br><br><strong>Model Notes</strong><br><br>I've included the Fusion360 model file. &nbsp;There are parameters that will adjust the dimensions of the handle, allowing you to change the size of the handle, and the hole for the diameter of the rope. &nbsp;I've found the default handle sizes are great, you may wish to adjust the diameter for the rope hole. &nbsp;This is the “RopeHoleDiameter” parameter.</p>
