Happy Halloween "Somewhat Stretchy" Bracelet

cults3d

As a fun addition to the Halloween costumes for grandkids, kids, parents, and grandparents, I've designed this Happy Halloween Bracelet that slips smoothly over the hand and onto the wrist. It's made to be somewhat stretchy, making it perfect for grandkid-resistant wear. The bracelet files included are sized at 58mm inside diameter, suitable for most of our grandkids. To accommodate older kids, adults, and grandparents (including my wife and me!), I scaled up these files using the Ultimaker Cura 4.2.0 scale function with values ranging from 1.1 to 1.3 across the X-Y plane. I've included both single-extrusion "Happy Halloween Bracelet.stl" and dual-extrusion "Happy Halloween Bracelet.3mf" files, as well as individual black "Happy Halloween Bracelet, Black.stl" and orange "Happy Halloween Bracelet, Orange.stl" files for merging prior to printing. Our bracelets were printed at 0.15mm layer height, 20% infill with no supports in both PLA and Ultimaker Tough PLA for added grandkid-resistant performance. To achieve a cleaner dual-extrusion print with intricate lettering details, I enabled the Ultimaker Cura 4.2.0 "Prime Tower" and "Ooze Shield" options, resulting in excellent prints (see attached photo). Even with these features enabled, Ultimaker Cura 4.2.0 reported using only 0.85m of bracelet color and 0.33m of letter color, making this a remnant print suitable for small spool sizes. Given the model's simplicity, I hope I haven't overlooked anything, but please let me know if you find any issues. Our family wishes you and yours a happy and safe Halloween! Designed using Autodesk Fusion360, sliced with Ultimaker Cura 4.2.0, and printed in PLA on an Ultimaker 2+ Extended, and PLA/Tough PLA on an Ultimaker 3+ Extended and an Ultimaker S5.
