Sweetie Bot 2560 : Modular Back Cover (Alpha Release)

This is the alpha release of Sweetie Bot 2560's modular back (and also the first of her source files to get shared, huzzah !)

It has four slots to slide in a module with appropriate attachments (such as the XRP saddle), and secure said module by sliding structural 6mm rods through the hole back assembly.

PLEASE NOTE : By alpha release, I mean this model is cursed and should not be printed (see the main SB2560 alpha 5 release for more details - link will be added as soon as published) The integrated supports don't really work because I'm still learning how to design integrated supports, the rails for the 6mm structural rods are undersized and have to be drilled to size (which is why the tube isn't inserted above - I forgot to enlarge the holes…), and the entire “take apart the entire back and slide out super long rods just to swap modules” is way too cumbersome to end up in the final release - dedicated latches are probably the way, but that'll mean relocating the four module slots so they don't interfere with the structural back rods…

If you do decide to print it, I don't have much to provide regarding prints settings. I'm an impatient gremelin who prints everything at 30mm3/s on a frankensteined CR-10, so whichever settings you're used too will probably give you better results than whatever I'm doing. I used PolyTerra PLA (cotton white). Just bear in mind, this is a big model and requires a 300x300x300mm build volume.

TL;DR : this is a snapshot of where Sweetie Bot 2560's developement stands in August 2024, NOT a “ready-to-build-your-own" release. Print at your own risk :(
