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 | edit source]

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

Tools needed[edit | edit source]

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 needed[edit | edit source]

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

Technical Specifications and Assembly Instructions[edit | edit source]

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 | edit source]

• 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 | edit source]
