Sebra Kili Baby & Jr bed Grub Loc

My Sebra Kili Baby & Jr bed was missing some of the Grub Loc fittings to fasten the headboards (shortend sides). I tried getting the spare part from Sebra, but they didn't have any left since the bed have been replaced by newer models (looking almost the same). My model is the version with plexiglass on the headboards. Attached image is from the instruction for the newer bed with the part of the bed where the fittings are installed marked by a red square. The newer bed has only the grub screw part, my bed has a bigger non threaded hole where the printed part goes and provieds the theading.

I have 3d printed versions of the screws, but I used metal ones, since M8 metal grub screws are easy to get hold of, and will make a stronger part. With the metal screw I think it will be close to as strong as the original version. I have 5 of the original fittings, and I'm not sure I would trust the printed ones to fully replace the original part.

You have to make your own risk assessment if you trust the part you've printed to hold the bed your child sleeps in. Use at your own risk!
