Description
SMARS LC (SMARS Lowest Cost). Goal of SMARS LC series of parts is to decrease cost of SMARS bot as much as possible for group efforts where classroom budgets are an issue due to building many robots at once. Solves problem of 3d printed stepper-mount screws coming unscrewed for SMARS - 28BYJ-48 https://www.thingiverse.com/thing:2778904 Print at 0% or 5% infill. Gently bend into place between stepper motors into holes, from the inside (see photos). Best to install when still warm, or warm later on a heated bed. If it snaps, try inserting it the first time while the 3D printed piece is still a little warm, or rewarm the part on a heated print bed first. Alternatively, the openscad source file is also attached and you can modify as needed. Straighten it out so it holds steppers firmly in place. You will need only 2 pins for a SMARS - 28BYJ-48 because one pin fills two mount holes. SMARS project was created by https://www.thingiverse.com/tristomietitoredeituit/about (Note, this part is called a "Samson" pin because it is pushing against two sides).
