Project Title

Project developed by aakruzel(talk) 4:46, 5 December 2019 (UTC)

This Open Source Appropriate Technology has been designed but not yet tested — use at your own risk.

Abstract

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.
2. Picture of completed print setup in Cura
   

Bill of Materials

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

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

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

Technical Specifications and Assembly Instructions

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

• 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

• 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%
