I've been 3d printing replacement parts for an old short course truck kit for awhile now and have found the front arms to be much stronger when you print them up on their side rather than flat. that way you don't get layer separation in the holes where a rod runs though when a shocked is applied. That said if i could still find parts for this particular kit i would snatch them up instead of trial an erroring my way to a decent part.
That makes a lot of sense, thanks a lot! Will probably try this next then. Yeah I found the parts online for like £10 so not too bad but it is fun to mess around and prototype things (: Thanks for watching and commenting!
Maybe if you make the big middle part ”softer” by adding big cutouts it would be able to deform a bit and absorb some of the energy, giving the weak spots a better chance to survive a sharp impact. Also is there room to beef up those weak spots? Maybe glue on some support?
@@autonoob yeah that would definitely be a good thing to test! Definitely space to reinforce the weak spots. Currently working on other projects now but if I come back to this one, will try to update the model based on your comment (: Thanks for watching and taking the time to comment.
@@firewaffle1 I have big plans on breaking my rustler soon so your r&d will come in handy :P I’m curious about giving plastic welding a shot if something breaks, to fix the original parts. Seems like it should be as good as new, but I’m skeptical.
@@autonoob oh nice. Would you be plastic welding with PLA or just whatever plastic is on the car like ABS I may to able to print the arms with PA-CF, which is a carbon fibre infused nylon. This is a lot tougher and more flexible. Unfortunately I can only print this on the printer at school but going to see if I can still use it and try some test parts! If I manage to do anything I will try to post updates here as YT shorts or community posts. If I have enough content maybe I can make a full video. (:
The strenght of PLA isn't very good unless you overbuild/overengineer everything but that makes everything much heavier and bulkier. Or use a combo of PLA printed material and some stronger material inserts like steel, nylon etc.
Yeah PLA is all I can print at home. I used to have access to a printer that could print PA-CF (carbon fibre reinforced nylon) and that would have been ideal. I'll see if I can still print on that one. If not, I love the idea of using steel inserts, thanks a lot! However the part broke at a place where it would be hard to put a rod through so will need to think about it carefully. Will definitely be looking to continue and improve on this project so will look into your suggestions. Thanks for watching and taking the time to comment (:

@@firewaffle1 i was thinking same as the parts so abs probably.
Make some videos I liked this one, I’m sure others will too. 👍
@@autonoob oh ok
Thank you (: got some more projects planned

hi what program did you use to model the parts in is it free ??
@@lewismadden8438 hi there I use Fusuon360. You can get a free trial or get a free subscription as a student (:
@@firewaffle1 thank you much appreciated unfortunately I'm not a student
Free trial will give you 30 days or something, not sure what else you can do otherwise /:
