So I play French Horn in my local orchestra and I really love it but what I also love is a Tuba so after I think since a half year I try to convince my parents that I wanna buy a Tuba just for fun from ebay. They refused but today they said with my own money I can buy one if I really want and now here is the problem I really want one but I don't have a use case for one I don't wanna stop playing French Horn but I really want to play Tuba because I love the sound so maybe you have a good advice for me.

Hi I wanted to cut this part in half because I dont have a 3d Printer large enough to print this part in a whole. And the Cut and connection function in Bambulab Studio isnt working properly for my purpose. So now I wanna cut this aprt in half and thancreate my own connection. How can I do that?

Hi,
I got an Altohorn from my great grandpa from WW2. And now I want to play it when we march. But now I dont know how to transpose from F-Horn to Eb-Horn. Can anyone help me there. I heard that you just go one note down is this right?
