During moving we broke one of the center supports of our bed.

I tried to find one online but they all had not enough stroke so I designed my own.

It's for sure slighlty overengineered but it does its job.

The parts were printed in BambuLab's PETG-CF (profile attached) and they turned out great. However I just used this material to have an excuse to finally test it. You should be fine with PETG / PLA+ etc. Just make sure to increase the walls and infill.
