 The missing piece in this setup is some sort of bracket to keep the TeleBT
 from flopping around on the antenna boom and loosening up the SMA 
 connector.  Thanks to Robert Garbee, we're happy to share this excellent

+## 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!
