The X1C case will get revised hot end holder modules, which will unfortunately require a small change to the base (so they will not be backwards compatible). It will also get the tabbed compartment latches. I'm testing the changes now, although I won't be using them myself (since the changes are small, I am testing cut down test parts to save on materials).
The A1 case will get a slightly (1mm) longer pocket for the small hex wrench, and also a revision to the grippers which help hold the needle tube.
Thanks to the great feedback on these designs, which has been very helpful to improve them! I decided to move these to the top of the queue since they are existing designs, but the other stuff like the Gridfinity watch cases, the Bento clone and other stuff is still being worked on, tested, or just requires a build guide.
