It will probably then cost around 12 euro excl shipping (I will sent them by normal post from The Netherlands)
Would there be any interest in this... ?
Use the poll so I can see how many there are interested and which model you would prefer.
I ordered a sample, so I can see the quality. Expect it to arrive within 1 - 2 weeks.
Both models have the same bottom, open frame with small feet which can be used to connect to lego bricks. The pcb is held to the bottom part by small clips. There is small cutaway area along the GPIO connector, so you can use that for a flatcable.
Top and bottom part are clicked together, no screws.
Model 1 : closed top with a large Raspberry Pi logo and some small vents
Model 2 : top with an open Raspberry Pi logo and some small vents, you could glue some thin plastic sheet behind it if you want.
