Foldable Ruler - Keychain
Hello everyone!
This is my foldable ruler for your pocket. Due to the linkages it is, possibly, extandable as much as you like.
Every single ruler piece is of 2mm thickness and 10mm wide. The lenght should be obvious.
How to print
I highly recommend to print this with a smaller nozzle (<0.4mm) so that all the details are more clear.
The linkages are designed with a wall thickness of .4mm, but i recommend a .25mm nozzle as well. It fits really nicely due to the new 2.5.0 slicer setting Arachne. (I absolutely love this setting)
I set the layer height of the single ruler pieces to .15mm and the layer height for the linkage to .1mm so it gets a little tougher.
For instance, setting a colour change at 1.7mm with a .15mm layer height will give you the look like in my pictures. Painting the front will of course also work just fine.
I printed mine with Prusa's Galaxy Black and Signal White PETG.
