The latest design can be found at Gitlab.What is it?45 Degree adjustable DJI controller mount for the bicycle handlebar. Can be printed without any supports.Why build it? Mounting options to buy were too expensive! And so far experience with DJI attachments were that quality is quite poor. Some designs where even 3D printed. Here are some examples $40, $50 - 3D printedAssemblyFreeCAD files have a spreadsheet with parametric values. Most important is to check the handlebar diameter and adjust value in the spreadsheet.StepsInsert M4 nuts into controller holder and clip pieces.Insert bolts into the knobs.(optional) I recommend using glue on bolt heads and nuts so they don't freespin if overtighened.Add something to prevent grip slipage. 3D printed plastic pieces can be very smooth and no matter how tight it is it can still slip. It is recommended to add a piece of rubber, electric tape or some sort of gasket to prevent clip slipping around the handlebar.Install the clip parts around the handle bar.Install controller holder and select the angle position.V3EffortCAD design (updates) - 30min 3D printing - 6hCost Filament - $1.5 Fasteners - $0.5Total - $2Change logReduced tolerances for angle adjustments to reduce movementAdded chamfered edge for the nut so it can be printed without supportImproved knob design so it's easier to gripThe clamp part is round instead of just rounded cornersNuts on the bottom clamp part are rotated so it's edge is further from the wallBOM1x Controller holder 1x HandleBar grip top 1x HandleBar grip bottom 3x Knobs (there are two different sizes but for the same M4 nut) 2x M4x20 1x M4x30V2EffortCAD design (updates) - 3D printing - 6hCost Filament - $1.5 Fasteners - $0.5 Total - $2V2 Change LogTighter fit for the ControllerWider grip around the handle barSplit the grip into two pieces so it's usable for not so flexible materialsBOM1x Controller holder 1x HandleBar grip top 1x HandleBar grip bottom 3x Knobs (there are two different sizes but for the same M4 nut) 2x M4x20 1x M4x30V1RequirementsHold Controller in a stable way Have adjustable angle Print without supports Use a single bolt to tighten around the handlebar Try new knob designsIssuesController holder had 2-3 mm slack and can move. Thin clip can split if nut is tightened too much. Small width of the clip doesn't grip enough and it can still spin.
