Material to use on 3D printing grab handle spacers for OEM luggage mounts?


Recommended Posts

Hi Everybody, I just purchased a 2007 RWB Interceptor with the factory bags and mounting kit. I learned only after trailering the bike home that I am missing key parts of the kit, including the spacers. I've downloaded the 3D print file from VFRD and I am researching where to have the spacers printed. 

 

Questions:

1. One company has asked for an approximate durometer spec for the OEM spacers to help them recommend a material. I certainly don't expect anyone can give me a durometer reading but perhaps some of you can describe how soft/hard/stiff/flexible the OEM spacers are?

2. The same company has suggested likely materials are: "ABS (what a Lego is made of), LDPE (low-density polypropylene) or maybe even Polypropylene (PP) but it tends to degrade under UV conditions.  My bet is ABS."  (I think ABS sounds too hard/inflexible). Anyone out there have an informed guess on this?

 

Thanks to you all,

 

Tarkus

Where are these files? What do these things look like?

 

If round spacers, why not aluminum? If not round spacers, why not aluminum?

 

Otherwise either a Nylon or PETG.

These spacers are almost like a really firm hi-density foam Material. 

 

I'd recommend using a TPU material from the FDM process. This will be the most cost effective approach. You will see some layering, but it will be durable.

My guess would be between 30 and 50.

 

The prototyped parts where you got the stl file from were printed through a company called proto3000

 

Www.proto3000.com

 

If you are interested contact Chris mcaloney as he's familiar with the parts.
