Mount itself is a bit tight, so care is needed to push it on. The 500 fits well. My Scicon 1/2 turn saddle bag fits, but can touch.
The mount part printed well and I fit on my saddle. It is a bit tight and I'm thinking that perhaps a full duplicate of the Cateye part isn't the best path since they are using a much more flexible injection moulded material. More thought, sketching, tinkering to come.
I've had a bit of trouble getting my design to work properly with the imported file. I'm still new to this! Also my mental image of the part I want doesn't want to work (design issue and a drafting skill issue). I've put this one aside for the moment...
Thanks for the images, I am going to lay blame on the tightness on a combination of Garmin and Shapeways.
That eighth-turn is the exact model I have used for every single Garmin mount I have made. I use it on my very old 800 and my newer 810 and also used it with a 500 my daughter had before that. Each and every one fits the exact same printed part differently. I am not sure if it is model related or what color plastic Garmin uses for the shell that makes a difference here.
Shapeways is very odd when it comes to black colored parts. Nylon in it's natural state is sort of translucent. All their colored parts are dyed in an acid based dye. Now here is how black differs. every other part is "polished" in a vibratory drum filled with water and ceramic bits. It makes the surface a bit smoother and it actually does have a more finished feel, then it is dyed in whatever color you ordered. Black parts are not sent through the vibratory polisher, don't really understand why that is, but it must be something about the black dye not penetrating the plastic as much as the other colors. They do not even offer black in a 'Polished' finish. So the dimensions, while being as exact as I can make them, are ever so slightly different for black versus all the "colored" version (I put "colored" in quotes as I am including white in that mix even though it is not actually colored).
Shapeways has a new material called black nylon, which starts with black nylon powder, but it is currently double the price of their normal nylon powder. It is currently only available to use in your own designs and not to the general public.

JonnyHK Someone has a Fizik ICS clip that is a lot less complicated than the Cateye version but for the life of me I can't remember who it is. I agree that the Cateye version is a bit over-designed and there must be a better way. I just haven't been interested enough to revisit it yet. If you get back to it and come up with a few ideas let me know. Here is what I found with imported parts in your own designs, once it is done and you import into your own design 1. make sure it is unlinked to the original (a small lock icon will show if it is linked) 2. for some reason once imported, Fusion 360 defaults to Sculpt rather than Model. I find it is much harder to add sculpted shapes to designs over modeled shapes. I guess if I were working on recreating the Venus de Milo, sculpting might be a better choice, but my small brain just doesn't like the complexity involved in sculpting a part to fit, so I always have to click Model.
