They're already rounded up (filleted) .
This is my first try @ceramics
1. What fillet (mm) would you recommend for this particular piece?
2. Do you think the debossed "CAPPUCCINO" text will show on the finished printed ceramic piece; or, will be filled up with the glaze and disappear as shown in the Shapeways' generated picture on the item's page?
Thanks.cascador
Tip #5: Joining faces should have a radius of 2.0 mm
A rule of thumb is can you snugly fit a 4mm (diamter) ball bearing into the corner of your piece? If there's a gap between the corner and the ball bearing, then it is too sharp. Sharp corners are likely to crack when heated.
From the design rules it should be at least 2mm, but I seam to remember being told 3mm. As you can see on that page, I don't think your text will survive well. I'm trying to figure out now why your 2D render shows no text, but your 3D shows text on both sides.The Mad Moder
