Someone said about posting a thread asking for interest elsewhere on here. Which is the best section ?
Just post interest topics on KLOV, BYOAC, Jamma+, Arcadezentrum (German forum), Gameroom.be etc.
The more interest, the cheaper it will be.
For this forum: post it on the Business Area subforum.
And I suppose at least 5 people in Holland would be interested, so one shipping of multiple doors to one of them will be much cheaper.
I´m interested in one coindoor.

could you post a photo of your Solid Edge drawing?. Has the coindoor one or two coin slots?
