    Anyone else find that the M3x35mm screws indicated in the build guide are slightly too long and bottom out in the motor?

    M3x30 are just long enough but only just.

    Could use washers to space out the M3x35 of course, but would look a little odd.

    I'm used to building things that can kill you if something comes loose at the wrong moment so still not entirely happy with the way the M3x30 fits, but it won't kill me if it comes out I guess :)

    I'll keep an eye on it and may end up reprinting the mount as you have done Alex, but I guess it will hold for now...

    I used a mini-drill with a cutting disc and shortened the 35mm screws down to 32mm.

    If you do it this way, chamfer the tip to make it easier to fit.

    If you intend to do that, one old trick it to put a couple of nuts on the shank of the bolt first, then after cutting, as you remove them it helps reshape the end of the thread.

    It's always better to chamfer the tips as Jason suggested.

    I'd say do both if you want, but I'd never cut a bolt without putting a nut on it first ...

    I got exactly the same issue.
    I think the holes on the motors are not deep enough, or better, the screws on the inside are too far in.
    Anyway, looking for a decent solution (washers just looks silly)

    If you don't fancy cutting down the M3x35mm bolts then you can buy M3x32mm or M3x33mm, just takes a little hunting down...
