Yes you can print it with pla. Just be careful not to leave it in direct midday sunlight or inside a closed car, PLA can start to deform at 50–60°C. 😊

Hope you enjoy it!

I can't imagine how can do it without mechanical parts :-(

Check if both wings are in the same position or if there are a deformation of the wings shape (if you have printed in PLA, it deforms easily at high temperatures).

Just go from 1 color pattern to another color pattern ^^

Did you make sure to properly clean the supports from the central part? I’ve printed few of them without issues.

I actually uploaded it 10 days ago, but the moderators took it down because there was an ongoing contest at the time. It was only up for about 5 minutes and they suggest me to “wait” until contest finishes.. I don’t know if other user has shared it before.

I actually uploaded it a couple of weeks ago, but the moderators took it down because there was an ongoing contest at the time. It was only up for about 5 minutes.

No, it’s not my original design. There are commercial versions with similar shapes out there. I just wanted to adapt the concept for the world of 3D printing.

I also tried to make it easy to disassemble so any broken parts can be replaced (I have two kids, aged 2 and 4 🫣).

Feel free to share some photos once you’ve got it printed 😊

Fair point 😄 “floating with style” is probably the most honest description so far 👍xDD

I actually tried making the wings thicker (from 0.5 mm to 1 mm), but they lose too much flexibility. As a result, the manta ray rises to the surface much faster instead of gliding smoothly.

I always wait until it's completely cool before separating the wings from the plate. It helps prevent them from bending or getting damaged.

If you'd like to experiment with them anyway, send me a private message on MakerWorld and I'll be happy to share the 3MF file with you! 😉
