I am currently working on an Ender 3 Pro Switchwire Conversion, using the Enderwire design from boubounokefalos.
He already added the 3D printable version of the top cover, but not the lower cover.
It uses the standard M3 threaded heat insert, as the rest of the design. It is sturdier than I thought and definitely sturdy enough for the top cover. It also uses the same printing settings as the top parts.
I did not include any tolerances to the dove tail joint; for me, they fitted perfectly. However, my Bambu Lab P1S is also calibrated quite well and handles small parts like this without the need for tolerances most of the time.
If a version with higher tolerance is needed, just let me know.
