These are brackets you can use to mount a TB6600 Stepper Motor Driver or Buck Converters with or without a display. I used these for the control board for the roundhouse turntable here.... http://1fatgmc.com/RailRoad/Turntable/Turntable-Index.html You can use the foot above or the following one to mount electrical boards like Arduino's or a buck converter without a display to a board. Use the holes in the board and these feet under the board. They will raise the board so that the solder connections under the printed circuit board aren't in contact with what you are mounting the board to. The foot above has a center large enough that a #2 screw will pass through it without contact. The foot above has a smaller center hole that a #2 screw will screw into. You can drill it out like the previous foot if needed. Above we see the feet alone being used under the smaller buck converter that is upper left. Brackets are being used to mount the buck converter with a display and to mount the TB6600 Stepper Motor Driver. You can find a link to the files to print this on my site here.... http://1fatgmc.com/RailRoad/3D-Printer-2/page-56.html .You can find all the files to 3D print this object and others on my thingiverse.com account ( HERE ).
