In German cities we have Repair Cafes and Makerspaces (Hackerspaces, Fablabs). Many of them are known to happily help out with 3D-printing. Maybe something similar exists in you area?

We really like this treasure chest https://www.printables.com/model/206656-treasure-chest-puzzle-box-update. Mechanism works very well and children were exited when solving the puzzle (as present box). There is even a video with its maker showing the variations and explains the unlock mechanism.

In 1995 we boycotted Shell for environmental reasons and it worked: https://en.wikipedia.org/wiki/Brent_Spar

Towing of the platform to its final position began on 11 June. By this time, the call for a boycott of Shell products was being heeded across much of continental northern Europe, damaging Shell’s profitability as well as brand image. […]

On 20 June, Shell had decided that their position was no longer tenable, and withdrew their plan to sink the Brent Spar […]

I understand your feelings, and I share them. Let’s stay strong and united, refusing to let fear or hatred divide us. Remember, we have allies in America who stand against extremism and are working tirelessly to promote justice and equality. There is a growing movement of brave activists, judges, and everyday Americans who are standing up against these challenges. It’s crucial that we support them and let them know they are not alone. Together we are stronger.
