About this 3D model

Remix of my own design. I had a lot of positive response so i desided to redesign it and use metal bearings to avoid friction problems i had with the 100% 3D printed version. Runs much smoother now! To build this you need these metric [mm] bearings: (amount x outer diameter / inner diameter / height - link) 1 x 47/25/12 - SKF 6005-2Z 4 x 16/5/5 - SKF 625-2Z I also tried to design it with 3d printed bearings - But did not work that well. I could get these bearing in an industrial store in my town for around 35 €. The bearing are standard sizes - so you should get them easy. Videos: I uploaded two clips to youtube.

If you print it with MakerWare the parts might not fit together - i found out that MakerWare does not care for the nozzle size. Thats why i had some space between every part on my preview version that was featered on thingiverse. I don't now how cura and other slicers work. You should test it with some small parts like GetrRad2A and GetrRad2B before you print bigger parts - they should fit together very tight. In case you own a Makerbot Replicator but don't have Simplify3D - i added a .zip-archive that contains all sliced .x3g-files ready to print. There is also a README.txt if you have problems getting the bigger parts printed on your R2. Designing: I use basic AutoCAD to draw my 3D stuff because i use it a lot on my work. It took me about 200 hours to design this siren. I added the drawing file if you want to make changes.
