can you guys upload your CAD Assembly? id love to see it!
did you guys have any revision to your design due to parts that failed? how did you insure the durability of your parts? |
Thanks for the link about Nylon. I'll have to look into that. I don't currently have a CAD Assembly. However if you want to look at the individual plastic pieces, you can download the stl files from thingiverse. I will try to see if our designer has one, but it may be a while as we are starting spring break.
As far as revision, we revised the motor mount from our original design not because of failure, but to make it vertical to take up less real estate. The only other part that was revised was the piece we call the ratchet hub. But not because it broke, but because the lead screw nut that it was attached to broke, and we didn't have another. So a groove was cut in the lead screw nut and an associated key was put on the new ratchet hub. We beefed the ratchet up quite a bit for fear it might shear off, so the fill I believe was 20% and the layers was set at 5.
