Well, seems in english "tasseau" doesn't exist... I hope the 1x1" is recognizable.
This are multiples connectors that I designed to add a slope to the roof of my rabbit pen.
There was already a rounded metal tube but it kept falling and didn't add a slope to the whole roof so the water would pool.
The main "T"-shaped connector as a round top so it doesn't pierce the tarp. Both right and left wings are inclined 10% wich makes an elevation of approx 12cm for a 1m roof span.
The third wing is straight so you can mount another one opposed to it for a better support (here I used my existing metal tube).
The other connector is a simple 2 piece hald-pipe designed to be connected to ~27mm tubes and safed with zip-tie.
In retrospect that's one of those small project where I would have spent less time using cheap metal bracket but oh well...
I've included the solidworks files if you want to change stuffs (I'm not gonna modify this one on request tho, I've had such a hard time with inclined planes on solidworks, ugh ;_;..).
You'll need 4walls (for a 0.4mm nozzle) and a lot of infill if you want it to be solid. My "T"-shaped connector ended up at 130g, a bit overkill, could do with less I guess.
I printed it upside down but it should work fine both ways.
