Assembly of the CoreONE, Step 7, "Securing the rear motor"
I'm basically at the near-beginning of assembly of the core 1, step 7, "securing the rear motor". The little standoffs on the z-motor mount keep breaking off when just starting to screw them into the bottom panel (not over tightening, but within the first turn or 2). It's like the M3x8 screws are not the right size. Now I'm not sure I can proceed with the rest of the build. I uploaded a photo.
I contacted support and they did't understand was I was referring to, suggested I was using the wrong screws (and had me verify with the cheatsheet), finally said they will send me 1 z-motor mount, and said my other mounts are probably fine. But just delicately testing if the M3x8 screw even goes into the remaining mounts, I'm saying no, I'm not convinced they are fine. And as for the screw size - this is the 1st bag of screws that are opened in the assembly (meaning, I'm not mixing screws around on a workbench).
I do feel like this is a "me issue". I'm doing something wrong. I don't have any other 3d printer, and this is my first printer! Any suggestions moving forward?
Circled in red are the broken standoffs. Circled in green are still in tact.

forgot to add: this particular part is on the z-axis right in the rear.
RE:
My opinion is they provided a defective part and should be replaced. Do you have a friend with a 3D printer that can print one for you? You can find the part here: CORE One printable parts under Base Assembly. Otherwise, just ask support to send you a new one.
Or you can try to glue it back then use a screw to pre-thread the holes.
