Here's the CAD I used to create my The 100. I tried to repurpose a lot of an Ender 3 V2, including the bed, mainboard, and steppers. Because of this, I had to make some changes to the design to suit my needs. I hope that other people in a similar situation can take parts of my CAD for themselves. I've also gone ahead and named all the parts that need to be printed with a P in front of them (Example: P Top Frame v4). Please reach out to me through Printables or on Discord (@boblikecheez) if you have any questions or need help!
I've used Onshape for all my CAD and here is the link to the document if anyone wants it: https://cad.onshape.com/documents/fba2f506c7eb0fcaca029abe/w/688cc69dd343bc5e6df2b0e8/e/3049ed8454c01b5397fad8f7?renderMode=0&uiState=64b41cd29285b05be8da048c
Here's my BOM mostly using Amazon but please note it's probably not complete and won't suit everyone.
