updated CAD assembly for trident

[hartk1213]

list of things i fixed

• Fixed all colors and materials they got messed up somehow in the previous update
• Organized and made proper copies of all the hardware..some were threaded, some were not, there were different models for the same hardware and now its all consistent so now you can run the bom export script and receive an accurate qty
• remodeled the leadscrews to be TR8X4 thread pitch as they were just m8 thread and didnt match the leadscrew nuts
• fixed leadscrew nuts that had left handed threads
• used copies instead of instances for everything i could, (fans, bearings, pulleys, chains, etc..)
• added accurate belts with teeth to the gantry
• there is probably more im forgetting

doing all this has drastically reduced the file size for the main .f3d assembly

previously it was close to 140MB now after all these changes its down to 47MB

Latest changes

this is the assembly that is being replaced

just an example of hardware that was cleaned up , there were various different models of the same hardware , those have all been fixed

added belts that are as realistic to the assembly as possible

pic 2 is what is currently on the repo

pic 3 is an example of various hardware that should be the same that was different. those are an m3 roll in tnut but they were 2 different models, issues like that have been fixed

pic 4 is just to nice not to share again :hehe~1: belts are now done as accurate in cad as they can be (imo)
