I need a printable 3D model of a Samsung S26 Ultra phone case that I can drop straight into Snapmaker Orca and send to my Snapmaker U1. The file has to arrive in both 3MF and STI formats, pre-oriented for PLA and kept within the U1’s build volume so I can go from file-to-print without extra tweaking. The back of the case is dominated by a Darth Vader design with his lightsaber drawn and the blade itself cut out from the case so the phone's color shows—that motif is the single most important feature of the whole design. Around it I want a subtle, functional textured grip on the sides and reinforced stability bars that protrude from the back of the case to prevent wobble on flat surfaces due to the camera without adding excessive bulk. A perfect fit is critical. Please match the official S26 Ultra dimensions, allow the usual tolerance for PLA shrinkage, and leave every button, camera and sensor completely unobstructed. Deliverables • Ready-to-print 3MF and STI files, aligned for PLA on the Snapmaker U1 • Any native CAD file or STEP you worked from so I can iterate later • A quick render or screenshot confirming the Vader design & cut-out, grip texture and stability bars are all present • Print settings you validated (layer height, infill, supports if needed) I’ll run a test print immediately; payment is released once the case snaps on smoothly, the Vader design and cut-out is clean, and all ports line up.
