Little disclaimer, this is not my model but I find it cool so I repost it here!
The original is from SphereFox on thingiverse.
It can be printed without support !
What you need to print :
To assemble it, you just need to insert each part into the rings. Small glue points may be required in some cases.
This really easy to mount to sockets, just have to slide it inside. No hardware required.
If other sizes are needed you can write me directly !
The author marked this model as their own original creation.
