Preliminary Student Design Warning
Note that this page is a preliminary student design and has not been vetted.
Care should be taken to read critically and weigh the evidence.
Remember non-tested and vetted designs should not be relied on, especially in matters of health and safety. Recommendations to improve this project follow:


  • non parametric
  • not looped
  • no holes for permanent fixturing

Tent Vertex Joint[edit]

Project developed by User:jcismith
Status
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.

Abstract[edit]

The purpose of this build was to make it easier and more convenient for individuals around the world to construct shelters with the resources available to them. The tent vertex joint accomplishes this by providing a sturdy point to join multiple poles for constructing a tent.

Bill of Materials[edit]

  1. Filament
  2. Design files (OpenSCAD and STL): | Youmagine Link

Tools needed for fabrication of the OSAT[edit]

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

Skills and Knowledge Necessary to Make the OSAT[edit]

  1. Knowledge of OpenSCAD is needed to manipulate the vertex joint if necessary.

Technical Specifications and Assembly Instructions[edit]

Print Directions[edit]

There is one .stl file for this print available to download.

Layer Height[edit]

It is recommended to print at a layer height of 0.1mm for a good quality vertex joint printed accurately.

Speed[edit]

It is good practice to print at slow speeds when producing quality prints, especially with this print due to the angle of the pole sockets. For the print above I used 40mm/s.

Temperature[edit]

I used Hatchbox 1.75mm PLA to make this print. A good temperature to print at with this filament is 185 degrees celsius.

Fill[edit]

I used 25% infill to ensure I made a strong, relatively light, good quality print.

Support Material[edit]

I printed with support material everywhere (touching the build plate and within the part itself) to maintain good quality when printing the angled pole sockets.

Removing Support Structure[edit]

  1. Using needle nose pliers, grab and tear support structure off from the pole sockets.
  2. Once all or most of the support structure is removed, sand until desired finish is achieved.

Print Temperature[edit]

For the PLA I print at 185 degrees Celsius, which provides me with precision printing and minimizes maintenance issues.

Assembly Time Estimate[edit]

Common Problems and Solutions[edit]

  • TBD

Cost savings[edit]

  • Cost estimate uses the base STL files on Youmagine. Varying buckle sizes can result in different costs and savings due to the parametric nature of the project.
  1. Total cost: $1.65 (82 grams PLA)
  2. Commercial Part: ~$10 [1]
  3. Approximate savings of $8.35 (83.5% savings)
