A couple of users have mentioned that they had some difficulty with pushing the ACME nut into the ACME nut holder because the center hole caused too tight of a fit. While everyone did get their Mill Ones put together, this did cause some sore thumbs. This is just a quick update to let everyone know that we have since added an extra bit of clearance to account for this.
We have been printing the newest version of the ACME nut mount for the last few weeks to go into kits, so these ACME nut mounts have already been phased into new kits being shipped out.
If you are planning on printing your own, the latest version of this part has been uploaded to Thingiverse.
