modRuler

Concept

A dead simple, but fully modular system to build an infinite ruler, a 3 axis ruler, a center finder or maybe a space station some time.

TLDR

Print the starter kit (a folder on the files tab) to get the concept. Just open your eyes big to see the small bumper in the hole :)

Background

The current (initial version) is created in a few hours and I post it now to enter in the measurement devices contest, but my plan is to improve it with time, so please print, comment, remix and set a reminder in your calendar to look back every month.

Design

With the help of the wonderful JSCAD web version and in a hundred lines of code the base concept is now kinda ready.

You can easily try it out, just copy the following code, set up a different module order and then export it.

Modules

Examples

C,F*3,P is the light blue guy on the cover photo. You can read it as: connector, then 3 pieces of full and a plug at the end.

I've tried out it as a crazy color change print, just for fun, but I don't recommend it for now until the whole project is cleaned up.

C,F,H,F,C is the center finder.

Code

Contact me if you are interested in the code.

Remarks

You might want to set high resolution for the export, but turn it of when you just tweak the settings or the code as it gets slow pretty quick.

There are issues with the generated model, but looks like that “Fix through the Netfabb” option of the Prusa Slicer get rid all of them.
