I present to you the towel rack for the bathroom, in PVC tubes assembled by junctions printed in 3D for the contest #DAGOMERLIN (that's good, I used my Discoeasy as well as the tubes and tools of Leroy Merlin;) ).

In short :
The file Openscad is parametric: you can change the diameter of the tube used easily (change the variable "Tube") if you know Openscad, otherwise ask me advice in the comments.
There are only two different types of parts to print: step join and end piece. The ring test.stl file is only used to test your pvc tube, or your parameter changes to adapt the design to another material.
The pvc tube is easy to work, lightweight, inexpensive and obviously resists moisture.
The assembly is done with only a screwdriver and wood screws, no need for "powertools", the screw taps the printed part and the screw head "enters" the room. The screw head does not protrude when the object is finished.
Materials and Cutting:
I used 25mm tulip tube (PVC irl for electrical ducts) because that's what I used for other projects, but you can use other tubes or rounds available in DIY superstores .
For the scale presented here of 1.80m of height with steps of 40cm, I bought in big surface of DIY 3 tubes of 2,40m for less than 5 €. Then I used the saw at the exit to make my cuts and cut the collar, with the tab box made available by the store to make straight cuts. So you do not even need to have these tools at home. In addition it is easier to transport once cut. You can even take a meter in paper if you do not have a tape measure at home;).
It will still be a screwdriver and wood screws / agglo 3mm (I used here 3x16mm screws)
I used Cura by Dagoma, with a layer thickness of 0.2mm and a filling of 17%. Printing is unsupported with these settings.
The elements are less than 15 grams, so for a ladder with 4 steps count 150gr max for the 8 junctions and 4 tips, which gives the final a customizable towel rack (height, width, number of steps) for a very low price. competitive.
For assembly, put everything on the ground then put the junctions on the vertical tubes taking care to put the holes for the screws above. This will be the back of the ladder.
For the same aesthetic reasons, put the tube marking (designation and barcode printed on the pvc tubes) at the back too.
Use 3mm wood / chipboard screws for assembly (3x16mm do the trick here).
Screw the steps firmly on the junctions.
Screw the end pieces.
Screw the junctions onto the uprights once properly positioned to have horizontal rungs.
There you go ;)
To finish :
The tips are curved, so it is possible to add anti-slip pads at the point of contact with the ground if necessary.
It is obviously not recommended to use this ladder towel holder to climb.
The Openscad sources are there. I mostly picked up the variables from my previous storage shelf project, but feel free if you have questions about the model, additions to be made or questions about editing to participate in the comments.
