JohnCh Posted February 4 Share Posted February 4 This forum has been strangely quiet given the number of people who 3D print, so let's start a thread for people to show their favorite print(s) they've made that's related to their passion for se7ens. The print doesn't need to be something you personally designed but should be a car part, tool, artwork or other related item you have printed. That means no searching on sites like Thingiverse and posting a bunch of things you think are interesting but have never tried. We can have a separate thread for that. Hopefully the items shown will give people ideas for their own projects. -John Link to comment Share on other sites More sharing options...
fastg Posted February 4 Share Posted February 4 Throttle pulley for the 90mm throttle body. The supplied one was huge and I was only getting about 1/2 throttle. I experimented with sizes until I got just the right movement. The 3D printed one lasted well, it could the 20 min track day sessions were fine, but the 30 min session it started to deform badly. I had to turn it to a new hole between sessions. Finally I sent the file off and had a CNC machined pulley made. Graham 3 Link to comment Share on other sites More sharing options...
JohnCh Posted February 4 Author Share Posted February 4 @fastg what filament did you use for the pulley? Link to comment Share on other sites More sharing options...
fastg Posted February 4 Share Posted February 4 It was a Prusa PLA+, nothing special. I believe using some of the newer filaments that can stand high temps it would have been OK. Graham Link to comment Share on other sites More sharing options...
JohnCh Posted February 4 Author Share Posted February 4 Under bonnet temps are pretty extreme for PLA or even PETG. Some of the major filament makers provide data sheets that include max temp ratings (claims?) before softening that are often helpful in filament selection. There are also some good YouTube channels that regularly test filaments to separate those claims from reality. If you haven't found this one, I highly recommend it. He has a PhD in Mechanical Engineering and teaches at the University of Budapest. His filament testing procedure reflects this background. https://www.youtube.com/@MyTechFun Link to comment Share on other sites More sharing options...
