Brief Professional Bio

I am Blake Peters, a junior at Principia College, and I am loving the open source movement! I am a computer science major with familiarity with Java, JavaScript, C++, and Python. I have constructed and designed an intensive, 4-week coding course called "Graphics" and have posted the majority of my works on GitHub. I am currently looking for a summer internship and an intensive coding project relating to open source 3-D printing code!

Reflective Paragraph

The open source movement is where people can publish work under certain licenses that other people can use to construct and build ideas off of by giving credit to the person(s) that they first based their project off of. I love the constructiveness of this idea! It allows for a community to prosper and thrive by allowing innovators to indirectly collaborate with strangers to produce something interesting or beneficial to society. Every piece from the Jellybox 2 build is open sourced and can be downloaded, modified, and improved by just giving credit under the correct licensing. My project was able to contribute to the movement by creating one more tool that will be using open source material to design certain projects for my 3-D printing class. I will definitely be contributing the the open source movement through code. I want to construct so many project that I have not seen on the major open source websites and want to dive deep into building at least one strong building block for others to take and upgrade!

and has smooth edges around the fins.

CaterpillarHead.png CaterpillarSegment.png Caterpillar Puzzle (head and segments) This is a creation that I made through Open SCAD, a language I'm starting to love! This is a fun project where you can print and add as many segments as you want to the back of the head and each segment. There is a hole in the back of each piece and a hollowed path for the connector part to move around in each segment, which allows the caterpillar to move up and down. Attached is the website for the details of this project:

OSAT Project[edit | edit source]

Pill Tray[edit | edit source]

Project developed by Blake Peters[1]

Abstract[edit | edit source]

  1. The pill tray is a request from Dr. John Gershenson who needed a pill tray counter. I wanted to create a tray that can be easily modified and rounded edges so the pills can be easily seen and sorted. This allows those that need a pill tray counter to request different sizes in length, width, and height. The only thing I found close to this was a pill dispenser on thingiverse. This was a challenging print to create in OpenSCAD, but definitely worthwhile!
  2. Picture of completed print:


Bill of Materials[edit | edit source]

  1. Only need filament: roughly 51g or 17.11 m
    1. All source files from open source CAD and all STLs:

Tools needed[edit | edit source]

  1. Jellybox or similar RepRap 3-D printer

Skills and knowledge needed[edit | edit source]

Technical Specifications and Assembly Instructions[edit | edit source]

  1. No special printing instructions needed for product
  2. Print time: roughly 3 hours and 3 minutes with 2000% scaling of OpenScad design.
  3. There is no assembly time needed, except for removing strings or strands that may have be hanging off the final piece.

Common Problems and Solutions[edit | edit source]

  • It took me a long time to figure out how to properly use polygons in OpenSCAD. I needed to understand this concept in order to make the tray have a ramp. There was a "simpler method", but would be more confusing to read, which would be to use a cylinder with only 4 edges and transform it in a way to represent a ramp, but I wanted to challenge myself and demonstrate my knowledge and passion for OpenSCAD. I was able to get the polygon function working and successfully completed my build.
  • It is easy to spend a lot of time modifying one particular portion of a complex OpenSCAD design. Remembering to focus on what is truly important and will benefit the product as a whole in the most effective way will produce the best results for perfecting any SCAD design.

Cost savings[edit | edit source]

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate of my costs: $1.28
  2. Commercial equivalent: $16.80


  1. $ savings: $15.52
  2. % savings: 92.38%
