KASSEUS — Kindle Paperwhite, 10th generation · 2018
Printing notes · plain

Material and scale
Import the STL in millimetres at 100% scale. Use flexible TPU and the settings recommended for your printer, filament and build plate. Rigid materials may not flex enough to fit around the retaining lip. STL does not store colour; choose your filament colour yourself.

Orientation and supports
Place the flat outside back on the bed, with the cavity facing up. Check the layer preview and retaining lip before printing.

Printable shell
Vertical exterior walls, smooth plan-view corners, a 0.4 mm 45° bed-facing chamfer and a 0.5 mm rounded upper rim. Rear contours affect the cavity only. Open edges have no retaining hooks. Retaining lip: 0.5 mm per side. This lip is intended for flexible TPU; use a physical fit test.

Device fit
Device envelope: 166.57 × 115.84 × 8.18 mm (height × width × maximum thickness). The scan-informed inner rear contour is preserved. Published dimensions do not certify physical fit.

Shell and fit
The base is 2.4 mm thick, with nominal 1.6 mm walls and 0.35 mm clearance per side. Walls can be thicker around the inner rear contour. Open edges: bottom, top. These broad openings preserve controls and Micro-USB access without assuming precise port offsets. This is an untested physical prototype: print a fit test before a final case. Mesh checks do not guarantee fit or surface quality.

Earlier Paperwhite 10 reference slice
An earlier plain Paperwhite 10 shell sliced into 56 layers without supports in Bambu Studio using a Bambu P1S reference profile, Generic TPU, a 0.4 mm nozzle, 0.20 mm layers, four walls and 20% infill. Estimated use: 57 g and 4 h 9 min. The reference profile flagged a bed-temperature warning; choose temperatures for your actual filament and plate. This is not a validated printer preset or a completed physical print.

Amazon User Guide, printed page 50: 166.57 x 115.84 x 8.18 mm; scan-informed cavity retained. Amazon User Guide, 2nd Edition, Product Specifications (printed page 50): 166.57 × 115.84 × 8.18 mm; use these rather than the rounded 167 × 116 × 8.2 mm catalog entry. Controls section (printed page 5) places the power button on the bottom edge. Retention remains a prototype assumption. Scan-informed update: approximately 9 mm corners and layered rear taper from PrintedForFun, https://www.printables.com/model/1699495-kindle-paperwhite-gen-10-tpu-bumper-and-3d-scan (CC BY-NC 4.0). Relative insets use the 2 mm scan outline as maximum, with depths scaled from 7.76 to the published 8.18 mm. The last measured outline is held to the rear for conservative clearance. See docs/kindle-paperwhite-gen-10-scan-analysis.md. Physical fit remains untested. Open edges: bottom, top. Access windows and corner retention require physical inspection. Physical fit remains untested.

Passed serialized mesh checks: dimensions, closed connected shell, winding, paired edges, nondegenerate faces, configured access openings and above-bed overhangs within 45 degrees.
Mesh checks do not certify physical fit or exclude every possible surface intersection.
