Seat Belt Button - Buckle Stop

prusaprinters

<p>[Update Nov.23, 2021 : I came up with a variation on the original design; this second version works betters on some seatbelts. See the additional files with “06” in the name.]</p><p>&nbsp;</p><p>You can mail order one of &nbsp;these for $1 and wait a week or three, or just print this one in 15 minutes for 5 cents.</p><p>This is the plastic button on your seat belt that keeps the buckle at a convenient height when the seat belt is disengaged. Since they have a tendency to break off and get lost, being able to print a replacement is quite convenient.</p><p>This button prints in four parts, so that the center “pin” can be printed in the strongest orientation (see photos).</p><h4>Installation</h4><p>The easiest way to install the button is to make a “pilot hole” in the seat belt using an awl. The idea is to form a hole in the belt weave by going between the fibers, and not cutting or tearing the fibers (which would weaken then belt). A tool with a slightly rounded as opposed to a pointed end is better for this.</p><p>Placement : The hole should be centered in the belt, and located about 18 inches (45cm) off the floor. <strong>Be sure to slide the buckle above the pin location before inserting the button!</strong></p><p>Assemble the “pin” side of the button by inserting the two halves of the pin into the “donut”, and then insert the pin into the pilot hole. This will be a tight fit, so using a pair of pliers to force the belt over the pin is helpful.</p><p>With the pin inserted, place the second half of the button over the pin on the opposite side of the belt. Squeeze the two halves together using the pliers. Done!</p><p>&nbsp;</p><h4>Print Instructions</h4><p>Print in PLA using the 3mf or gcode files provided. All four parts can be printed at the same time. The general settings are :</p><ul><li>0.2mm layer height</li><li>0% infill</li><li>perimeters = 6</li></ul><p>Orient the parts on the print bed as shown in the photos.</p><p>I should note that some people think PLA does not perform well in a hot car in summer heat, so printing in PETG might be preferable.</p><p>Note there are now two different versions, the “02” and the “06” versions; use the version that works best on your seat belt.</p><p>&nbsp;</p><h4>CAD</h4><p>&nbsp;</p><p><a href="https://cad.onshape.com/documents/557ac2c7f2f3f17907adf018/w/1609b897e3c1fd4e7d349ab0/e/e1d6083828f5f907e3dfc6e6">https://cad.onshape.com/documents/557ac2c7f2f3f17907adf018/w/1609b897e3c1fd4e7d349ab0/e/e1d6083828f5f907e3dfc6e6</a></p><p>&nbsp;</p>
