Hello,
I am making a toothbrush with a disposable brush. The shape of the tootbrush itself is finished, now I just need the brush part. It is supposed to be a platform to hold the brush hairs. I was just wondering how I can create thuis platform with the exact dimensions of the “hole” in which you place it. For your convenience I have provided a screenshot and the .shapr file.
If you could help me that would be extremely appreciated.
Kind regards,
Jonathan 🙂

The video says it all. I purposely made copies to show the various steps.

And here’s the Shapr3D file for your info. Note: the platform piece here is not scaled down at all.

Here’s a better way using **Project**.

Thank you for the help thus far, I was also wondering if it is possible to have the platform the exact same height. Now it’s sticking out a bit on the upper side. Thanks in advance

I projected the inner curve on a plane and created a closed box to extrude-remove the upper portion of the platform. The 2nd video shows the projection part in more detail.

That’s brilliant work Mike, it’s always worth reading your posts. I never thought of doing that before even though it’s so simple.
