Shortly, you shall be receiving a strongly worded letter from Harley Davidson telling you to cease and desist from any further misuse and appropriation of their trademark. Lol
Think I'm kidding........ they've done it for less. ��

 

Printing big custom things is very time consuming and very subjective to customer taste.

But, printing useful parts, especially smaller and non-available parts can be very profitable for someone with a 3D printer.

A possible one might be the bit that breaks off the brake light switch when you forget to use the shim in the lever when working on the hand controls. If you could make a replacement piece to go into the switch for just a few dollars, you might have quite a customer base.

Things like that. I'm sure there are others. That's simply the one I can think off for a Harley off hand.

 

If you could rig it to work with the holder in post 16. And make it a jiffy stand disk. It would be a great place to store it.

 

Wire it up with an led light.
