Linear Slider for REV Robotics extrusion

thingiverse

The REV Robotics linear slide kit v2 is solid, but it falls short of being truly exceptional. Take a look at [http://www.revrobotics.com/rev-45-1507/](http://www.revrobotics.com/rev-45-1507/) for more information. Assembling the numerous pieces just right to achieve low friction on the slide can be quite a challenge. Furthermore, we have encountered issues with the end caps breaking twice when the lift operator fails to stop in time or the bearing covers come loose - an understandable oversight considering we should use limit switches for the lift. This design aims to utilize the same extrusion and bearings from the lift kit while simplifying assembly, adjustments for a low friction slide, making it stronger, and avoiding special parts like hex head bolts. Adjusting scaling by 1% increments in your slicer (2% = 1.02) will allow you to perfectly fit the slide with your extrusion and 3D printer, but once dialed in, mass production becomes straightforward. My original design fits the Andymark 1515 extrusion flawlessly, but not the REV Robotics 1515 extrusion - the channels are slightly smaller. The "Linear Slider Simple" is the easiest to fit with scaling, however, if your extrusion accommodates the original version, use it instead, as it has less play. Mounting bearings strongly involves first bolting on the slider to the end of the extrusion, then drilling a hole through the extrusion using the bearing holes as a guide, and finally securing both bearings with a single bolt on each side. This design was created with Tinkercad.
