It's Relaxasaurus! There's a couple options for you to choose from. Happy Relaxasaurus is cute and can be resized to whatever you like. Relaxasaurus Holder can be used for utensils, pens, sharpies, etc. The 100% size will hold an object with a diameter of 16.5mm or less.

If you need to resize the holder version, here's how I do it in bambu:

• Right click Relaxasaurus and add a negative part cylinder. set the cylinder to 16.5mm
• Select Relaxasaurus again and resize. if you click on the cylinder after resizing him, it'll show you the diameter he can hold.
• Once done, delete the negative part
