Description

This is a ball that folds up and fits in your pocket. It is a fun and entertaining general purpose tennis ball sized folding ball.

It is a print-in-place 1-piece ball that folds into a 12mm thick disc. It can be deployed and collapsed quickly and easily. 100% printed - no hardware, fasteners, or adhesives required. No support is required.

This version of my folding ball has a middle core that serves two purposes. First, it increases the overall mass which helps with throwing, and second, it strengthens the ball by creating a cross member in the middle of the deployed ball.

I have posted a "Light" version of the same ball here... https://than.gs/m/1179490

Your material selection and slicer settings will determine how durable and strong the printed ball is. I recommend a durable and flexible material like PETG or something stronger. You will want to print with a minimum of 4 walls and 100% infill.

Safety Note: As with any plastic toy, please supervise children and pets while they’re playing with it! While the ball is durable, it’s still 3D-printed, and material could break off.

Print Settings:

Material = I recommend PETG but any material should work.
Nozzle = 0.4mm
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Top and Bottom Layer Count = 5
Infill = 100%
Ironing = Not required, but can be enabled to improve layer separation after printing
Brim = No
Support = No

Very nice! My first print was high speed, low density and it came out "OK" but two rings broke for lack of support. This one I printed per the instructions (took two hours) and it is just perfect. Now I am wondering if there is a lubricant that can be applied to make it work more smoothly.

A great design that prints well with the settings provided by the maker.

Very fun and easy print. First time I tried color change on my machine and worked flawlessly. Ty

Very cool! But I would remove from the description that dogs and cats could play with this. PLA is still a fairly brittle plastic and could be easily ingested by a pet. My brother's cat died because it got it's hands on a broken piece of a 3D print. The piece got lodged somewhere in it's digestive tract and didn't make it out of emergency surgery.

Awesome, thanks for posting. Lubricant is a good idea. Perhaps some light synthetic oil. But I have also found that they loosen up nicely with a little use. Thank you.
