Is that $85 for all parts?
Calculate the extra cost if someone doesn't own a 3D printer (or doesn't have access to one) or soldering gear.
Right! I believe that assumes you already have necessary tools, and it certainly can't take into account the cost of your time or the cost of mistakes along the way.
It's a fair call from a practical point of view. But I'll also say you're very likely to keep using your 3d printer for all other things, so not fair to put all costs into this one project.
Besides there alternatives to buying the printer: friends and print shops. Besides where I live a few libraries let you use their printers (and I believe materials) at no cost.
Well, printing externally costs a few bucks so that is not really the problem here.
Soldering is more complicated but that's more a learning curve problem than an equipment problem.
As someone who has tried soldering with the wrong equipment (and thoroughly stuffed it up), it's both. Learning with the right equipment however is a lot easier than with the wrong stuff.
And 3D printing externally can also be a bit of a trial and error process if you're new to the whole thing.
In terms of 3D printing it depends a lot on the quality of the model (which usually is pretty good in projects like this, unlike some thingiverse models) and the quality of the printing service. A reputable service will basically always produce good results,only the hole in the wall private garage services are sometimes problematic from my experience.
With soldering you are absolutely correct, it is far easier to learn with more expensive equipment (but this is still far cheaper than 3D printing, decent soldering stations go for less than 120 bucks these days), but it's still comparably cheap - but not easy to master. Takes a lot of time.
