Minimal pegboard paper towel roll holder: fully parametric!

This paper towel roll holder is designed to be as minimal and easy to print as possible. The STLs here are designed to fit into a 1" centre-to-centre 1/4" diameter pegboard. Everything in this model is configurable in OpenSCAD (see below the "About this Model" section below).

Printing instructions

You'll need to print both the left and the right model.

Notes: 

• This model needs very minimal infill. I use lightning infill and it's practically empty. 
• In PLA, using 0.6mm line width and 3 walls the holder is adequately strong. I also use 3 top/bottom layers, but this is less critical. 
• It's designed to be printed with the flat portion of the arm on the build plate.
• The pegs on this model require some small supports. 
• The supports can be a little tricky, but with the right settings they'll pop right off. I use traditional supports usually, but I've had some luck with organic / tree supports too. The real key is to make sure the pegs are not fully surrounded by support material. Specifically, for the support settings (terminology may vary between slicers):
     - Use a support brim
     - Enable a support interface with some space
     - Make sure there is no support horizontal expansion.

About this model

This object is a sample from my Pegmixer project written in OpenSCAD. Printables has poor support for OpenSCAD source files and limited license options. You can get the source files on the Pegmixer GitHub repo along with the library and instructions and how to add the dependencies.

Download the OpenSCAD source files and create your own STLs rather than just getting the pre-rendered stuff from here. Everything about this model is parametric, so you can tweak everything very easily in OpenSCAD from the pegboard spacings and hole dimensions to the arms and towel roll. Making it just right for your own context is just a better experience! Also, I think the license I use for the Pegmixer library and sample files is more appropriate. I'd encourage you to use OpenSCAD, but you do you if you want to use the STLs.
