Summary My first upload. A simple colourful ring stacker for young children. Made it for my 11month old and she loves it. Print the rings in whatever colour you want. Colours in picture are what I used, with a glow-in-the-dark purple for the base. The rings spin very freely, while fitting/sitting well, on the pole too. Printable on 150x150x150 beds. Print Settings Printer: DaVinci Jr 1.0 Rafts: No Supports: Yes Resolution: 0.2 Infill: 30% Notes: Use supports for the rings as they tend to be a little messy on the bottom side for the curve without them. I use a 30% infill so they're a little stronger in case someone stands on them....you may want to go more or less. Post-Printing May need a little clean up on the bottom sides of the rings. Check the inner holes for any sharp bits for little finger safety. It should go without saying, check all the prints for any sharp edges or parts that may hurt your child. I don't accept any responsibility if your child gets hurt from using this. Print and use at your own risk!
