This is a baseplate to fit an 40mm PVC drainpipe. I am going to use it as a mount for an table-leg. It has no problems with wet conditions so it is suitable for the bathroom and outdoors.

I printed everything with PLA but Ngen-flex is more suitable for the end-stop.
I added a ring to solve uneven legs. It is easy to make thicker in blender or your slicer. It is also possible to make a ticker endstop. (takes more time)

I printed with a higher temperature 220grC to improve the bonding between layers.
