Spider Web Nipple Ring Shield

pinshape

These nipple shields are designed to stretch the nipple slightly. The ring itself is 6mm tall and 12mm in diameter. Two versions are included - a smoothed version for printing as is, and a squared version for modification. I found that rounding edges in Sketchup once modified can be frustrating, so the squared version is provided for those who may need to make adjustments. There is no hole through the hub because these were designed with the bar riding on top of the ring. Normally, I would have put an indent in the ring to help center the bar, but the piercer didn't do it straight, so that doesn't work here. I've been unable to persuade my girlfriend to let me post photos of these being modeled yet. Print Settings Supports: Yes Resolution: 0.2 Infill: at least 60% for strength Notes: This model is better suited for SLA printing or get it printed through 3dHubs, Shapeways, etc in SLA since I don't have a free SLA printer. This does require supports, but the supports would fuse to the outer ring making removal difficult. To solve that, I raised the model 3mm off the build plate and added support underneath. That makes for a much better support structure that is easy to remove. Post-Printing If this is printed on an FDM printer, you will need to sand the underside of the web really good to get a smooth surface. Start with 60 grit sandpaper and work your way up to at least 220 grit. If you have patience, you can keep going as high as you want. The higher the grit, the smoother your surface will be. I learned this by doing it myself. I use Sketchup for modeling. Initially, I drew the design as a flat 2D surface and extruded that up. Getting it into the curved shape took some time. I tried the SketchyFFD and Flowify plugins but neither worked right here. Finally, I created a semi-circle and used the Sandbox Drape Tool to transfer the 2D pattern onto the surface of the dome. After that, the Joint Push-Pull plugin was used to extrude the curved surfaces upward. Next, I used the RoundCorner plugin to round over the edges. A little cleanup made the model water tight and it's done!
