If it is < 15 grams, is that with steel or ti or al bolt? I would think that an al bolt would be adequate if torqued correctly. In fact, maybe a coarse nylon screw directly into the mount?
If the bolt material selection could lower the weight by 3 or 4 grams to make it the "lightest" Garmin mount, it would be worth even more money to us weight weenies.
Sub 15g was meant including stainless steel bolt and nut... I indeed wanted to make it as light as possible, because weight is rather important factor to some and being the lightest should help me when it comes to selling
I never thought about the titanium bolt and I'm vary happy you pointed this out... I will definitely try to offer Ti bolts, probably as an optional extra
I will think about the nylon bolts you mentioned.. We've been producing bolts in the past, though those were meant for different application... I shall recalculate if it pays off... Producing moulds for each new part it's quite an investment you see

Well picking up a material is quite a process... There are many factors that define the final decision... material has to function well on your product, it has to be appropriate for your given moulding process, etc.
I wanted to make it using carbon fibre reinforced nylon composite however I suspect it won't be appropriate as it tends to crack if stretched, isn't elastic enough ( remember, mount has to stretch over the bar at installation )..
Next alternative is some kind of PEhd (high-density Polyethylene) or there is one other material that we've been testing for plastic springs, hard and elastic at once...

Also, since he's just in prototyping phase I'd imagine he still has to test multiple materials first. Since he's going to be molding them, he has to have the mold made first, then tested with different types of plastics (because the strength of an injection molded material will be different than the same material that has been 3D printed).
First I will pick a few types of plastic, then After my moulds are done, i'll do the testing to see which material handles best
And indeed, material characteristics are different if a product is injected or 3D printed... characteristics of a printed product can be similar to the ones of an injected product, however only to a certain degree. So I guess that's also my plus, comparing to Raceware's mount
OK, some of you asked for a photo, how it will look on a bike... these are the closest I cold make, showing you how it should look like in real life...
P.S. This photos clearly show what prototyping is all about... The gap on the loop that comes around the bar is faaaar to wide
... it is a design fault and it will be corrected... the gap is going to be 2mm wide max
