Hi, could you release new drawing? Thanks!
I think the measurements for the holes are still the same.
But the new design seems to be a little more rigid.
I need to know the dimensions of the actual build plate, not the supporting structure and cannot find it anywhere.
Hi guys, please receive this file.

Hi Do you also have the dimensions for A150 heating bed ?
This drawing is awesome and will come in handy. My A350 bed is so distorted on 2 corners that I can’t print any item larger than about 175 mm x 200 mm. Since my printer is out of the warranty period, it would be nice if I can use the full capability of the machine. I’m sure I’m not the only person with this problem. The original cast aluminum bed is not very stable after repeated heating & cooling cycles.
I’m in desperate need for a new, level bed so I can print a large electronics case for a custom 3D printer I’m building. I plan on machining a new bed from aluminum mold plate because it’s more stable at higher temperatures and resists thermal stress & deformation.
Does anyone here know what the maximum allowable weight of the print bed is on an A350?. Ideally I’d like to eliminate some of the open spaces in the bed and make it more solid but also know the weight will be a factor in loading the steppers as the bed travels during use. Any bed weight specs & stepper loading info from the Snapmaker Design Team would be helpful and very much appreciated.
Thank you in advance for you input.
I’ve been considering doing the same, so I am curious how this works out for you.
There has been a bit of discussion on the stepper motors:
Anyone have technical data?
Specifications Overview
Snapmaker Specifications (Google docs)
I don’t recall reading a weight allowance. I remember reading that the rotary module requires new linear modules, but don’t know whether that is for accuracy or power. If power, then you can use the shipping weight of the rotary module (and chuck, though it is one of those small light ones) for an idea of what too-heavy is.
Thanks. Is this a newer version of the print bed shipping with new A350 machines? If so, is there any history on the performance of this newer design?
Sorry for digging this up.
For some reason I ended up modelling the different platforms according to the dimensions shared here.
I hope it helps the community to design interesting stuff to mount on the platform. 
Have fun.

Didn’t see yours until just now. I made an OpenSCAD model for the bolt pattern:
/*
(c) 2022 - Onno Benschop, ITmaze
This OpenSCAD design implements the SnapMaker A350
build platform. You might use it to avoid bolts during
machining, or to build an alternative platform that
matches the existing bolt pattern.
If you want to implement this with actual holes
and threads, update the "mount" module to change
the properties for each hole.
Design based on

// This module can render either side of the build platform
Show_Platform_Top = true ;
// How much space to allocate to each hole
Bushing_Diameter = 10 ;
// Set the work origin to the center of the platform
Position_at_center = false;
module __Customizer_Limit__ () {}
$fn=360;
module mount(x,y) {
translate([x,y,0])
circle(d=Bushing_Diameter) ;
}
translate(Position_at_center?[0,0,0]:[150,160,0])
if (Show_Platform_Top) {
// The holes on the top of the platform

Hehe, looks like I wasn’t the only one then
