    Yes, really very budget, congrats to the builder. To be honest I fear when I pull hard (and in a real car I do so) the brake will blow up in my face ;) Please do not understand this as an offense @early_m, just my thoughts in terms of stability

    I cringe a little when my 19 month old starts pulling on it, but its actually pretty robust and there's not much force going through it as it's an e-brake.

    I didn't think it was too shabby for less than a fiver! (ignoring filament costs)
