16mm tube connectors

I have made these 16mm tube connectors, so my kids and I can build a skeleton frame and put a blanket on top.
Made the square design, for better printing and strength abilites.
No support is needed.
Have fun like we do. 😃

Print instructions

Printed in PLA @ prusa settings. 0.2mm speed and with 15% infill.
215C and 60bed.
I have printed in various colors, so its easier to find the different connections.
