MOST Delta filament as guide.JPG This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the discussion tab. The course runs in the Fall semester. It is not open edit.

Project Title[edit]

Project developed by aakruzel(talk) 4:46, 5 December 2019 (UTC)
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.


  1. A bike seat is a simple, but necessary part of a bike that holds most of the weight of the biker. In many developing countries, biking is the most common mode of transport. Additionally, a mud flap is important for keeping the rider clean, especially during rainy seasons.

Bill of Materials[edit]

  1. Available plastic that can be 3D printed, and glue/adhesive
    1. Link to all applicable files needed to create part. [1]

Tools needed for fabrication of the OSAT[edit]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Depending on type of bike, an allen wrench or screw driver may be needed to attach seat.

Skills and Knowledge Necessary to Make the OSAT[edit]

  • General 3D printing knowledge is needed to make parts.

Technical Specifications and Assembly Instructions[edit]

  1. Recommended Print Settings: Temp=210, Material=PLA, Layer Height=0.3mm, Infill=25%
  2. Print Time Estimate: 4 hours 20 minutes
  3. Assembly Time Estimate: 15 minutes

Common Problems and Solutions[edit]

  • A common problem is the tolerance for the assembly is too tight. To solve this, use a thicker wall thickness and use sandpaper to create a snug snap fit.

Cost savings[edit]

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimated Cost(57g): ~=$1.14
  2. Commercial equivalent, Seat $17.98 [2]]
  3. Commercial equivalent, Mud Flap $19.95 [3]
  4. Cash Savings: $36.79, Percent Savings: 97.14%
