Not so much show, but rather use... - I present to you my very first 3D Design and Print!
The design, mesh and export to stl took place in FC, the printing was outsourced.
In total it took me about 3 weeks from start to export... However, at the same time I had to make myself familiar with FC (reading the wiki, youtube, asking questions on the forum, etc...). Also I didn't worked every day on it, furthermore sometimes I got frustrated with my lack of skill or the (sometimes) clumsy interface of FC, so I let the project rest for a couple of days. But I finally finished it and I'm overall very satisfied!
