Linear Slider for REV Robotics extrusion

thingiverse

The REV Robotics linear slide kit v2 is good, but not great. See: [http://www.revrobotics.com/rev-45-1507/](http://www.revrobotics.com/rev-45-1507/). There are lots of pieces to assemble just right in order to get a low friction slide. Also, we have had the end caps break twice when the lift operator fails to stop in time or the bearing covers pop off or... I know, we should use limit switches for the lift. This is an attempt to use same extrusion and bearings from the lift kit but simplify assembly, simplify adjustments for getting a low friction slide, make it stronger, and avoid special parts like the hex head bolts. You should adjust scaling by 1% increments in your slicer (2% = 1.02) to get the slide to fit perfectly with your extrusion and 3d printer, but once you 'dial it in' it's easy to make in bulk. My original design fits the 1515 extrusion from Andymark perfectly but not the 1515 extrusion from REV Robotics - the channels are fractionally smaller. The "Linear Slider Simple" is the easy one to fit with scaling, but if the original version can fit your extrusion then use it instead, since it has less play. The strongest way to mount the bearings is to first bolt on the slider to the end of the extrusion, drill a hole through the extrusion using the holes for the bearings as a guide, then use a single bolt for both bearings, one on each side. This thing was made with Tinkercad.
