A part like this is begging to be done on a resin machine. You can’t beat them for the kind of shapes and tolerances you’re working with here.
I’d give it a go on my FDM machine, but I have .8 nozzles loaded right now - no hope haha.
I’d be happy to turn a few of these out in resin if you don’t have a machine, would only ask for the freight cost.
You’re welcome - glad to see you have it really sussed out. Finding something that works for you and knowing it won’t just up and disappear off the market (as many fashion frames do) is excellent.
Can see the optician side as well - they have an established process and deviating from that is unwanted faff. However, they are perfectly capable of ordering a lens to a customer given spec. A short ‘if this doesn’t work then lol you suck’ disclaimer is all it would take to make the sale.
Resin is well within reach of the casual hobbyist now - we’re talking a couple hundred dollars to get an entry level machine, and a little extra coin for the materials/consumables. I have a (now old) Mars 3 that is ticking along beautifully.
Safety/PPE/ventilation is the main downside compared to FDM. It’s a stinky job but you can’t fault the results for presentable and functional parts. These things can print stuff like screw threads and other teensy features perfectly.
Offer always stands if you ever want something to demo and can’t get anyone more local to help :)
