+## Printing Hints ##
+
+All of our 3D printing is done on [Lulzbot](https://www.lulzbot.com/) 
+printers, and the brackets we sell are printed in ABS.
+
+If you look closely at the STL file, you will notice that there's a slight
+chamfer on one side of the bracket around the square hole for the antenna
+boom.  You should print the bracket with this side "down".  The point of this
+chamfer is to counteract the usual "spreading" of plastic on the first layer
+of a print.  On a Lulzbot TAZ printer, this chamfer causes the resulting
+printed part to have a nearly perfect corner, which means it's ready to use
+right off the printer without any sanding or scraping to fit required!
