I am still collecting information, before I can make a precise estimate, but please expect >> 10k €.

One part is that this needs a new stencil, production preparation (there is one person sitting
one day to fill the component feeders) and the production run itself. Which would be 1 day
renting operator persons plus machine operation time. And someone has to test and potentially
fix all the devices. This will be somewhere between 5k € and 10k €.

Another major factor in this calculation is that due to the delay and our problems there is now
the Librem 5 ready for preorder at 599 USD.

This makes it unlikely that there are still enough Openmoko friends who prefer to buy a GTA04A5
board at the planned price of 444 € or a complete Letux 2804 at 584 € plus VAT. This price was
calculated to cover all cost under the assumption that everything goes well (with some reserve
for problems - but this has already been used more than completely).

So a more realistic price would be 244 € for a GTA04A5 board and 384 € for a complete
Letux 2804. The production is ca. 60-70 boards limited by the remaining components. So this
means another ca. 13k€ is missing because of this effect.

If we find a gratuitous donator covering the additional cost (and risk that it will fail again),
we could give it a try to build the final batch of devices. We could even invite the donator
to participate and watch the production run.

Thus, a rough estimate is that in total it is ca. 1% of what Librem 5 has collected... Or
one 10-pack of Librem 5 + 30 inch Monitors.

So if someone wants to donate or knows someone :)
