Busy Board Spiral Spinning Rattle

cults3d

I built a busy board for my son Jack's first birthday and I added some 3d printed elements for some colour and because I knew they would be fun for him. This is a spinning rattle with spiral cutouts and is probably his favourite item on the board. I printed some small white cubes to be the rattling element inside the spinner but any small bead could be used. The side brackets need to be strong. I printed these in PETG with a high infill - somewhere between 50 and 85% should work. I've even seen my 3 year old standing on it. The mounting holes are slightly elongated so you have some adjustment available when tightening the screws which you might need to get the spinner running freely. I had no problem at all adjusting it so that it was free running.
