This is a super simple bracelet that you can print in NinjaFlex. It's very light and flexible and sized for a loose fit on a woman's wrist. It's a good starter thing to print once you've got NinjaFlex working on your printer. You can try resizing if needed but be aware that this will affect the strength and flexibility of the print. I might later throw up some different sizes that maintain the thickness. Update: The lovely people on the FreeCAD forums helped me smooth things out a bit and I added some sizes (unstretched bracelet circumference of 7.5", 8.5", 9.5").I suggest the following settings: Important!! Use blue painter's tape! I've made several bracelets and they destroy kapton tape, even these thin little things. No bed temperature. No brim. (important, as it's impossible to remove) Set all speeds to 13 mm/s and retraction to 1.6mm (plus or minus a bit, depending on how hot your tip gets - you can also try cooling down the tip to reduce strings and going with 1.4mm/s). Lots of skirt (I think mine is at at least 2 layers and this is because it takes a long time for the stuff to flow) 2 or 3 perimeters/shells (in reality you'll only get two out of this bracelet but I think I accidentally had mine set to 3) You don't want infill but this bracelet is small enough that it should automatically not generate any infill. This is not a structurally strong print and it wasn't meant to be, so try not to pull on it like crazy. While it is stretchy, it will snap at the thin points.
