Detroit Diesel engine

This is a file create by IM9241221 on Sketchfab in FBX format. I have converted it to stl format and resized to 1/25th or close to it. Best printed with resin printer. Note the fan on my engine didn't come out well as a few small parts. I am going to redo the fan and print it separately. So, print with caution, you have been warned. I will add the fan later

The original files are found here and credit to the designer, awesome job and very detailed https://sketchfab.com/3d-models/detroit-diesel-engine-9cb230e23a7248778c1daa0b031ddeba

Update: 3/28/26 Resize the Detroit Diesel to be closer to the 1-25th scale, Rev D

Update: 3/20/26
I redid the DD, made it into 7 separate parts plus the tranny in 2 options. It looks good so far. Rev Bs and engine block Rev D, individual or one zip file

Update: 2/15/25 Added 2 piece set up, made this easier to print or play with in cad programs, although this is less detailed due to reducing mesh size. New files under Rev A.

Update: 4/20/24 Added 2 fan versions, one has a 3 mm stub and the other with no stub. This based on the original fan, I redesigned the whole fan to have a bit of thickness, enough to be able to print.
