We should get a "3dprinting" topic - problem here: "must start with letter"
The problem you can not make a tag or topic with a number as first letter. It would be great if admins can find a solution or manually create one. There is a great huge community around open source printers what would be potential users.
Thanks for supporting that feature - I have no clue where I can ask for it other than here as I am pretty new on steemit. So would be great to get the topic set up maybe manually by an admin!
I try to write a whole 3d printing tutorial at stemmit - you can find it here:

I think you must contact some admin like @ned , i am not sure.
Hahaha, I know how you feel. Whenever I want to do tagging for my posts on 3D-printing, I have to use "print3d" instead of "3dprint". Hope they will get it up soon!
