Hydreon RG-9 Pole Mount Bracket Adapter

prusaprinters

Lunatic Astronomical's AAG CloudWatcher now has a version that supports the Hydreon RG-9 rain sensor.  They have a very good pole mount bracket to attach the AAG CloudWatcher and the optional Anemometer but they do not have a solution to mount the Hydreon RG-9 with them which is the ideal setup.I found a pole mount bracket that looked like it would work, the Anteenna TW-CR Pole Mounting Bracket (https://www.amazon.com/dp/B075WXP655) and designed an adapter for it that would attach the Hydreon RG-9.The adapter is in two pieces: the bottom piece wraps around the TW-CR and has a hexagon post with a 6.4mm hole through it;  the top piece slides onto the hexagon post and the TW-CR is then sandwiched between the top and bottom piece.  A ¼ - 20 x 1 ½" (M6x1 40mm) hex bolt then holds it all together along with a couple of washers and two nuts (or a nylon lock nut) to keep the bolts from coming loose.Because the top piece fits inside the bottom piece and the post is a hexagon as apposed to a circle the pressure of the bolt seems to be sufficient to hold everything together securely using just the one bolt.If you wanted a more secure connection you could use epoxy and glue the adapter parts to the TW-CR bracket before final assembly.  I felt this was not needed and would only complicate things if the plastic eventually deteriorates as it is exposed to the elements.I printed the adapter using 0.15mm QUALITY settings and Prusament PETG Urban Grey with 100% infill for added strength as it will be going outside permanently.  Overall print time was 3h25m and used 13.57 m of filament.Design created in Autodesk Fusion 360 Personal
