3D model description
Made this beautiful engagement ring case for my fiancee last christmas, just in time for Christmas Eve proposal. Now, you can too!
Case dimensions 36mm (H) x 55mm (L) x 55mm (W) when closed.
Lid hinge is designed such that the lid can stay up-right to the casing body without generating too much friction. Click-snap feature along the tip edge of the lid. Sand it down as required, but I found mine one printed okay.
You can mount a lithophane portrait with dimensions of 35mm x 35mm x 3mm thick, at the back of the lid, then supported by the 2 layers of Lithophane support inserts and 3x M3 counter sunk screws.
I use this free lithophane maker here:
The ring cushion will be a separate insert to the casing body. Best to be printed with TPU filament as it is elastic.
DISCLAIMER: Avoid printing the ring cushion with hard material, otherwise it can potentially scratch your ring.
Recommended ring dimensions for the current ring cushion design:
Width of the band all the way around = 2.2mm
Depth of band = 1.5mm
Outside diameter = 19.5mm
Height from top of diamond to outside base of shank = 24mm
Following screws will be required to complete the assembly:
2 x Pan Head Screws M2.5 x 16mm long - for fixing the hinge.
3 x Counter Sunk Screws M3 x 6mm long - for fixing the lithophane on lid.
My case body and lid was printed using CCTREE Copper Filled PLA filament for elegant effect.
Apply few coats of Hycote spray for the fine polishing finish:
