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)
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.
I uploaded two clips to youtube.
I used Simplify3D to slice all parts. 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.
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.
Most parts can be printed with standard settings - No Raft, No Support.
Except of following changes:
- Gehause3 - change filament color while printing to get the text highlighted
- GetrRad2A+B - print it solid, needs to be strong
- GetrRad4A+B - print it solid, needs to be strong
- Kurbel1 - use brim to prevent warbing
- Kurbel2 - print the top layers solid
- Rotor3 - print it with high resolution (0.1 mm) and raft to get clean props
- Schraube1 - print it 3 times
- Schraube2 - print it 6 times
- Schraube3 - use brim
If not every part fits after printing you may have to use some abrasive paper.
Parts like the rotor should be sticked together.
