prusaprinters

Update 2024-05-15: There is a new version that includes two side ramps for additional rainwater collection. It's available for the 2"x3" and 2 5/8" × 2 5/8" sizes so far.This diverter attaches to a downspout to provide an outlet for rainwater collection.There are three different downspout sizes available:2"x3" (nominal) downspout, a common residential size in North America. The actual internal dimensions are 83mm x 57mm (8.5mm corner radius). Also available with side ramps.2 5/8" × 2 5/8" (nominal) downspout. The actual internal dimensions are 68.5mm x 68.5mm (8.5mm corner radius). Also available with side ramps.New: 3" x 3" (nominal) downspout. The actual internal dimensions are 76mm x 76mm (8.5mm corner radius).Design featuresThreaded outlet connector that is recessed into the body. This allows you to swap outlets (or put a cap in for winter), and minimizes the risk of damaging the main body.Easy access for maintenance by unscrewing the outlet connector.Internal drainage hole to direct water down and out instead of through the outlet threads.Storage compartment on the opposite side for a second outlet adapter (swap your winter cap for the summer adapter). Not on the smaller 2 5/8" version.Outlet adapters can easily be remixed.Pre-"drilled" attachment holes for #6 or #8 screws.Outlet adaptersCap: use this to keep all of the water going into the downspout.GHM straight: threads on to a garden hose (attach the female end of the hose to the male threads), exits perpendicular to the flow of water in the gutter. Use a washer for the garden hose.GHM 50deg: threads on to a garden hose (attach the female end of the hose to the male threads), exits with a 50 degree bend downwards. Use a washer for the garden hose if needed.New: GHM 90deg: threads on to a garden hose (attach the female end of the hose to the male threads), exits with a 90 degree bend downwards. Use a washer for the garden hose if needed.22mm straight: fitting for a 22mm hose, exits perpendicular to the flow of water in the gutter.22mm 50deg: fitting for a 22mm hose, exits with a 50 degree bend downwards.Printing instructionsChoose the diverter body corresponding to the size of your downspout.Print the main diverter body as oriented in the .stl file (upside down). I recommend a brim to secure it to the build plate.Print any outlet adapters you'd like to use, always as oriented in the .stl file.The angled adapters require supports.Installation instructionsCreate a space in your downspout of about 60mm for the diverter (it's helpful to have the device with you and measure exactly). Make sure to leave enough downspout for the screws to attach.Add the diverter into each piece, making sure the orientation of the internal slope allows water to flow down and out the side.Make sure the bottom downspout is between the outer and inner shells.Use #6 or #8 screws as to secure it (one on each side is probably fine). For metal downspouts, consider self-tapping metal screws.Screw in the outlet adapter or cap you want to use. Optionally store another one in the slot on the opposite side.You may be interested in my Rain barrel hose clip.MaintenanceIf you need to clean any debris out, just unscrew the outlet adapter, and push the debris out of the way or use a hose.It may be more difficult to do this on the version with side ramps.NotesIf you want to send the outflow of your rain barrel back into the downspout, take a look at my Downspout gutter injector (un-diverter) for rain barrel, the “inverse” of this model.Like most of my models, I've designed this with OpenSCAD and it is fully parameterized. If you would like a modification (e.g., dimensions, angle of the internal slope, screw hole sizes), just send me a message.
