Idea For Improving 3D Printing Slicer Config Sharing

Being new to 3D printing I’m constantly fiddling with my slicing settings. From one print to the next and from one filament to another, I’m constantly trying new settings. I think it would be nice to have a simple way to share and save the configurations used for each print that I and others can reference when I share my finished prints. My idea is to use a slicer’s settings export feature to save those settings and then associate them with the finished print online. I’ve been using both Slic3r and Cura and I share some of my prints online at Thingiverse. I’m thinking of an automated way to push the config file to something like Github’s Gist servece and then converting the raw settings file to something human readible like markdown that can then be posted into the description of the print on Thingiverse. Would be cool to see plugins for slicers that do this sort of thing automatically.

Filter lines by matching string or regex in Sublime

Nice little Sublime plugin by davidpeckham that allows you to find all lines matching a string or a regular expression in Sublime. After installing, on Mac, you’ll search to include lines with Regex ⌘+K then ⌘+R. That will bring up the search box. To include lines with a string use ⌘+K then ⌘+S.

Remove Duplicates From List – Quick and Easy

I needed a quick way to take my several thousand plus list of numbers and remove all duplicates. Just a one off task where I didn’t care about the original order of the list, only that there should be no duplicates. Enter python! Here’s how I did it.

  1. Open Terminal on Mac
  2. Type “python” and execute
  3. Format my numbers in an array like [39213123667, 532092995671, 659203651894,… in a text editor for easy copy and paste
  4. Use python’s set to remove duplicates and then convert back to a list and print out:
listWithDuplicates = [39213123667, 532092995671, 659203651894,...

# sets are unordered collections of distinct objects
deduplicated = list(set(listWithDuplicates))

# used this to see how many duplicates were removed

# print out list to start doing real work

How much time does being a seminary teacher take?

I was curious about how much time it would take to be a seminary teacher when I was asked to be a seminary teacher on June 17, 2014. Since I was running my own business at the time and tracking all of my work hours by project, I added seminary as a project in my time tracking app as well.

I think the amount of time it takes to be a seminary teacher in one year is going to very from person to person based on several factors. This was my first time teaching seminary and the class was an early morning class. So how much time did I spend on seminary in one year?

488.5 hours total

Let’s break that down since that is not the amount of time I spent teaching.

283 hours 5 minutes teaching in class, setting up class, traveling to/from class.
152 hours 5 minutes preparing lesson plans, study, etc.
51 hours 32 minutes for teacher training.
19 hours 27 minutes for administrative and other tasks.

Let’s use 2,087 hours as our standard for a years worth of full-time work. That means that my first year teaching seminary equalled about 1/4 of a full time job. Fascinating stuff. Hope this helps others who might be getting into teaching seminary for the first time and wondering just how much time they might expect to put into the endeavor.
