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 printed

Assembly

FreeCAD files have a spreadsheet with parametric values. Most important is to check the handlebar diameter and adjust value in the spreadsheet.

Steps

• Insert 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.

Change log

• Reduced tolerances for angle adjustments to reduce movement
• Added chamfered edge for the nut so it can be printed without support
• Improved knob design so it's easier to grip
• The clamp part is round instead of just rounded corners
• Nuts on the bottom clamp part are rotated so it's edge is further from the wall

V2 Change Log

• Tighter fit for the Controller
• Wider grip around the handle bar
• Split the grip into two pieces so it's usable for not so flexible materials

Requirements

Hold Controller in a stable way Have adjustable angle Print without supports Use a single bolt to tighten around the handlebar Try new knob designs

Issues

Controller 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.
