replacing back-screw standoffs

[sundog]

does anyone have a 3d model and/or the exact dimensions of the back-screw standoffs?

I've managed to break both of mine and I'd like to print some replacements if possible.

If you still have them, you can put some double sided tape that's used for cell phones one them and they'll stay put.

I broke mine off and they've held firm with an inch of the tape under each and I've removed the bottom a bunch of times.

My problem is that they have each physically broken into multiple pieces. I don't think I've managed to find all the pieces in order to try this.

I'll break out the Calipers and measure one in a little bit

It's been 30 years since drafting class and if you have any problems reading it let me know.

I know, it's terrible but it should give you a good idea.

Ohhhh, if you tape it down, I don't think you'd need the little alignment tabs. Super Glue might work too.

This is awesome - thanks so much for doing this!!

I'll see about putting this through openscad later this afternoon to get some initial prints done - I'll let you know how it goes.

Thanks again, you're the best!

Okay, finally managed to squeeze in some time to give this a try, and...it worked!

I've published the STL on thingiverse under a CC0 license here: https://www.thingiverse.com/thing:4226648

All I did was lay it out in OpenSCAD using the measurements you provided converted into millimeters. The OpenSCAD code is:

Code:

// Pinebook Pro back screw standoff
// Version: 1
// Date: 2020-03-16
// Author: pine64 forum user sundog, based on
//         measurements provided by pine64
//         forum user Michael
//
// License: CC0

// resolution settings for display in openscad
$fa = 1;
$fs = 0.4;

// back right corner standoff
difference() {
   cube([6.9342, 7.9756, 1.2700], center=true); // the main piece
   cylinder(h=1.27,d=2.286, center=true); // the hole in the main piece
}

translate([(6.934/2)+(1.1684/2),0,(1.27/2)])
   cube([1.1684, 2.0574, 2.1844], center=true); // centered tab

translate([0, (-7.9756/2)+(0.7620/2), (0.9144/2)])
   cube([1.9812, 0.7620, 1.27+ 0.9144], center=true); // side tab

// back left corner standoff
translate([10, 0, 0])
   difference() {
       cube([6.9342, 7.9756, 1.2700], center=true); // the main piece
       cylinder(h=1.27,d=2.286, center=true); // the hole in the main piece
   }

translate([10, 0, 0])
   translate([(6.934/2)+(1.1684/2),0,(1.27/2)])
       cube([1.1684, 2.0574, 2.1844], center=true); // centered tab

translate([10, 0, 0])
   translate([0, (7.9756/2)-(0.7620/2), (0.9144/2)])
       cube([1.9812, 0.7620, 1.27 + 0.9144], center=true); // other side tab

This is my first OpenSCAD model, so if anyone wants to clean it up and refactor it into something nicer, feel free

Thanks again for your help, @MIchael - my Pinebook Pro is fixed and I couldn't have done it without you!
