Paper towel holder

About

If you have a piece of 20mm PP tube then you can make this towel holder. The main idea is using as long tube as you will need and adding the printed inner thread to fix it in place. You can take the short tube to hold the butt napkins or use the long one to mount 2 or 3 big rolls of kitchen paper towels. 
My tube has 20.4mm outer and 13.7mm inner diameter. Using printed threads and screws fairly optional if yours tubing has another dimensions.

Printing

• The holder itself: 0.2mm layer, 4 walls, 15% infill, PLA, PETG (I'm using ABS). Nothing special.
• The threaded parts: better to use 0.9-0.12mm layer height with 0.4 nozzle, it's good for nice threads. Used light blue ABS from 3D pen set that look like shit but still works. There is 0 and 0.2mm thread tolerance parts.
