One can never expect CAD to be the same in real life, it just doesn't work like that. With every project I've done, I'm always reminded of that lesson. Printing some of the steering components gave me difficulties, but it's all worth it because one learns from failure. I'm hoping this prototype works as I anticipate, if not I'm going to start working on version_4. I don't know how many iterations I'm going to make, I hope no more than 7. Either way production continues, most of it has been delayed due to my lack of time to redesign some parts, but I'm still on schedule.
