Abstract

  1. This device is used to collect a small fecal sample for testing. This can range from DNA testing to testing for disease. Fecal matter can tell a lot about someones genetics and body function. This device is appropriate for OSAT because it can be used in developing countries and palces like Africa for testing for diseases. The device that has been developed is similar to the design shown below, but costing nearly 99% when compared. It was developed for Kijenzi/ HESE.

A similar design can be seen here: https://www.universalmedicalinc.com/30ml-fecal-containers-attached-screwcap-with-spoon-self-standing-with-skirted-conical-bottom.html?campaignid=1035133172&adgroupid=50759560077&adid=245051569142&gclid=Cj0KCQiAz53vBRCpARIsAPPsz8V5c9daZSkCPJudSDz1J26pmK8SsQacdqsNFslrOjxcuPnFdXrl-OoaAnxFEALw_wcB.

Bill of Materials

  1. PLA or similar Printable material is all that is needed. PLA would be most appropriate due to its environmentally friendly nature
    1. All of my STL and SCAD files can be found at the following link: https://www.youmagine.com/designs/fecal-sample-kit

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer

Skills and Knowledge Necessary to Make the OSAT

  • There were no "special" skills or knowledge used to create this device. The only tool i used was the OpenScad cheat sheet for reference on some functions

Technical Specifications and Assembly Instructions

  1. To assemble this project, it is fairly simple. Once it is printed, it should just screw together with the printed threads. I did use 2 sets of pliers to get the threads to loosen up a bit do to the variance in my printer. To print this project, make sure to rotate the base.stl 180 degrees so that the bottom is on the build plate, as i designed it upside down.
  2. Print Time: 1.5 hours
  3. Assembly Time: 10 seconds
  4. The images shown show the 2 printed parts and what they look like when assembled.


Common Problems and Solutions

  • The biggest issue is the threads being printed. In my design i was able to get it to work the first try, but they can still be improved. I was unable to get the threads to be "cut" from the material instead of being added like they are. If the threads had more of a cut feature to them where they were the same diameter as the inside of the cylinder this may solve the issue. To combat this issue, i printed the pieces fast to try and eliminate the effect of the overhangs.

Cost savings

  1. The cost to make this part is only $0.24 when using a $20 1 kg roll of PLA. It only uses 12 g of material.
  2. A commercial equvilent can be found here. It costs $131 [1]
  3. $130.76 saved or 99.89% savings
