It’s indeed an undertaking heavy in an upfront investment and I’m sorry it’s been hard for you to continue this process.
I’m sure Framework buyers are not foreign to paying some premium for a unique item, so I’m confident you’ll be able to recoup the investment if you don’t price the items too low.
It comes to my mind that an RGB LED matrix module for the Framework 16 sold about 120 pieces at about 70-80 bucks each. Another example is this Etsy listing where people are happily buying the item for 50+ Euros that another person is selling on the forum for 15.
That’s another advice I’d give - post the items for sale on both Etsy, Ebay and classifieds for your country in addition to the forum - you’ll probably get some sales through those channels as well.
And of course, if you’ll ship to Europe, I’ll purchase one for myself as well.
