Little project i worked on as my partner is a fan of Ghostbusters.
Included the font i downloaded for anyone who wants to personalize theirs too as i have in the images shown (note: my gf's name STL isn't included lol)
One in image shown is 100mm but object is 150mm to allow a bit of resizing. Also the top half of the red 'No' sign is partially missing as the red ran out before finishing it as i'd bought a 10m sample to test how the logo worked.
Additional work to tidy up some of the 3D model was done by a great 3D artist named Chris Thompson whose page can be found on the following link https://www.myminifactory.com/users/chrisofedf
