<p>This is a Bumper Case for a Texas Instruments SR50 (or SR51A) calculator</p> <p>(from the mid 1970's)</p> <p>I printed these in 2 types of flexible filament:</p> <p>Gizmo Dorks Flexible TPU - TPU with a shore hardness of 96A</p> <p>3D Solutech Real White 1.75mm Flexible - TPE? shore hardness unknown</p> <p>(Printed face down using tree supports in Cura)</p> <p>You may need to experiment with percent infill for good flexibility,</p> <p>so it's flexible enough to get onto the calculator.</p> <p>What worked for me was to insert the bottom of the calculator</p> <p>(from the front of the case), then one top corner, and then the other top corner.</p> <p>My FreeCAD design file is included.</p> <p>Designed in FreeCAD 0.19, sliced in Cura, printed on a Prusa clone using OctoPrint</p> Category: Other
