These parts are modifications of the originals that I struggled with during assembly. Plus a couple of joined up pieces for those able to use a larger printbed like the CR-10 and the CR-10 Max.

The most important one is the charging handle bolt merge. Print this with a 5mm wall. This is to make the handle solid and able to take the punishment of being used. I used real springs in mine, which is probably why the handle broke (And the infill was only 20%) Printing with a 5mm wall means that the infill can be left at 20% but the walls completely fill the handle making it solid.
