In the build guide under the Clutch Drive section, the instructions says the following;

take one hot-melt nut and melt it into the top_hat_v2's horizontal bore and then thread a screw into it.

I noticed that the bore for the hot-melt nut is smaller than the one used in the Mounting Dowel Assembly (mounting_dowel_v3). I used a slightly smaller M3 nut (4.2mm wide, 3mm tall), but this barely fits into the top_hat_v2's horizontal bore. Could you please specify the intended nut's dimensions to ensure a proper fit? Clarifying this in the documentation would help avoid assembly issues for others.

Here's an image of my top_hat_v2 using the nut specified above:
