I don't see any previous message from you. I don't happen to remember whether you have to be a member to post in the first place; I think you do. Yes, you got to be a member and I am for years now. In the first post I forgot the [OpenSCAD] in the topic. After the second post I received a reply that my post ist waiting for approval because I am a "moderated member". I have no idea why I am. Nonetheless, thank you for the advise on BOSL2 and the nightly build.
