Indicator adapters front and back for CBR300R

For my taste the CBR's factory indicators are far to beefy, so I replaced them with some Barracuda Mini Vipers. But that is actually easier said than done, given the fact that there are no indicator adapters available that wouldn't leave a massive recess in the fairing. – Time to fire up the A8. :)

As mentioned above, the adapters are designed to fit the Barracuda Mini Vipers, which have an 8mm wide and ~19mm long thread with a pitch of 1.25mm. The diameter of the indicator's arm is 16mm. Any indicators with these dimensions should fit straightaway.

I used mike_mattala's brilliant screw and nut generator to create the threaded parts. The bolt consists of two parts: one with an inner thread (pitch: 1.25mm, matching my indicators), the other one with an outer thread (pitch: 1.25mm). The whole assembly is completed by a nut (pitch: 1.25mm, matching the bolt) to which I just added a fixed washer.

How I Designed This

Step 1 (front):

Removed one of the factory indicators

Step 2 (front):

Slid a piece of paper into the fairing and traced out the shape of the hole/indicator

Step 3 (front):

Scanned said paper and created a vector graphic in Affinity Designer

Step 4 (front):

Imported the vector graphic into Blender and extruded it into the third dimension

Step 5 (front):

Printed said extrusion

Step 6 (front):

Wrapped painter's tape around it, inserted it into the fairing and traced out the shape of the fairing

Step 7 (front):

Removed the tape from the extrusion and scanned it

Step 8 (front):

Cleaned up the scan and used it as texture in Blender

Step 9 (front):

Still in Blender, I cut the model to the shape of the fairing

Step 10 (front):

Added the hole for the indicator and added some details in openSCAD

Step 1 (back)

Used the base shape and created the adapter in openSCAD :)
