Note, i haven't printed and tested this in it's entirety yet! Let me know if you have issues
A modular toilet paper shelf to make your own cloud. I was inspired by the design here: https://www.thingiverse.com/thing:3113094 but wanted to create it in a way that i could customize the cloud shape whenever i wanted.

This shelf is multiple pieces that you can choose from, print, and assemble to get your own custom toilet paper cloud of any size you wish. This is made to fit the 125mm diameter rolls i had.

All pieces will work together in any order. The connectors are located such that any 2 pieces put together will have the same effective curve to hold the toilet paper rolls. The shape of the cloud you make will depend on the combination pieces used. If you use just the 30 degree pieces then you'll have a hex grid, if you use just the 45s then you'll have a square/diamond type grid, etc. Combinations of angles will work fine but you won't have a clean grid but this isn't necessarily a bad thing.

Be sure and print 2 end caps along with whatever other pieces you like.
Included:

End cap - to, uh... cap the shelf nicely
L connector - a 90 degree section of a circle. note this piece does NOT have a screw hole and is mainly meant to finish off the end of the shelf, along with an end cap. You do not have to use this though.
45 Degree Left side - the left side of a joint of two 45 degree angle pieces. This means that if used in series the rolls would create a 45 degree line (from horizontal) going up and to the right
45 Degree right side - same as above but the right side, and if used in series makes a -45 degree line from horizontal going down and right.
30, 20, and 15 degree pieces that work in same fashion as the 45s, but with the indicated angle instead
Flat Connector - in series these let you line up rolls horizontally

In the renter I show, from left to right: End cap, L connector, 45DegRight, 45Deg Left, 45DegRight, Flat connector, 20DegLeft, 15DegRight, L connector, End cap.

Screw holes in this design are 5mm diameter so most any screw should work, they are 10mm deep so be sure and use a longish screw. Of course going into a stud is best but using mollies should be fine too, toiletpaper isn't THAT heavy.

The joint gaps are 0.3mm which should be ok for most printers. This means you ideally shouldn't have to sand anything to get the joints to slide together.
