3D printed Bike Seat (with Post)[edit | edit source]

Project developed by Wayne Helminen WayneHelminen (talk) 11:50, 6 December 2015 (PST)


Abstract[edit | edit source]

  1. I have designed a small Bike seat and seat post that can be used to replace an original bike seat. I believe this could be beneficial to people that don't have access to conventional means of purchasing bike parts. The print is done in two parts so that it can be done without supports and takes approximately 5 hours for both prints, but the strength of the seat has not been tested.

Bill of Materials[edit | edit source]

  1. 1.75 mm filament (amount depending on size of seat)
  2. Plastic epoxy to secure seat top to seat
  3. Foam for comfort


Tools needed[edit | edit source]

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

Technical Specifications and Assembly Instructions[edit | edit source]

  1. Using the STL's provided you can slice the parts with the settings that best fit your printer. I printed the seat post and topper (module named "Seat Post") upside down, which does have a little overhang, but produces a pretty nice print. I then printer the seat (module named "Seat" and epoxied the two parts together. If you make the seat a different size there is a little bit of code manipulation required. Most variables are explained, but the small cut out for your legs have to be manually adjusted, but this can be done really easily.
  2. Print time estimate - 5 Hours
    1. File:BikeSeatRev2.scad
    2. File:BikeSeatRev2STL.stl
  3. Assembly time estimate - 20 Minutes

Common Problems and Solutions[edit | edit source]

  • There is some overhang present in the prints so if you can't get a quality print, you could try using supports.

Cost savings[edit | edit source]

  • Print Cost - <$1
  • Time - 5 Hours
  • Commercial Bike seat and post - $25
  • Savings of 96%
