    I bought a mini-v gantry and it doesn't seem to fit (too loose) but the measurements are all spot on according to the CAD object and drawings I can find.
    Here is the only drawing I can find:
    http://makerstore.cc/wp-content/uploads/2015/03/Mini-V-Plate-11.jpg

    Looks like the CAD in the store puts the spacing at 31.8 instead of 31.9. Is that a big enough difference?

    I saw a forum post where OpenBuilds modified their part because it was loose. I also see "v3" printed on the part in the store.

    Are there updated CAD drawings/files?
    Can someone measure their mini-v and provide the hole spacings they have?

    Did you buy it from openbuildspartstore.com or makerstore.cc?

    <_< neither
    They're trying to tell me it's made for 2040 and not 2020 which makes absolutely no sense what so ever.
    My rail is OpenBuilds though xD

    If I can't get them to rectify it, I'll have to modify it or make my own.

    Don't know who "they" are then, but consider getting genuine plates from openbuildspartstore.com - then
    a) you know its the right stuff and
    b) if there is any issue, they won't give the runaround, customer service team will sort out any issue in like literally no time :)

    It would be real swell if I could get an answer the question I asked :)
    Here is my revised question:
    What hole spacing is required to use mini-v wheels with eccentric spacers on an OpenBuilds 2020 extrusion? I plan to make a custom plate.

    Oh! Right! Click Resources above, OpenBuilds Parts section has sketchup, step and Solidworks libraries

    32.0mm is generally a workable number. I can’t offer true +/- tolerances as that can vary slightly with the extrusion runs but 32.0mm has never let me down.
