Wanted Objects

From RepRap
(Redirected from List of wanted objects)
Jump to: navigation, search

This page collects suggestions for useful things for a RepRap machine to make. If you are a designer and wish to help out the project, pick something from this list (or WhatWouldYouMake), design and test it - then add it to the List of available files and remove it from here.

Where you can, try to put things in the right category by precision International Tolerance Grade that the object must be made to, and the materials involved, to help inform developers.

Things marked with a ^ are particularly desirable.

Mechanical components

  • Tracks and bogies
  • Wheels systems enclosures
  • Pulley wheels and blocks
  • Chain
  • Knobs

  • Generic playing piece pawns to replace the lost pieces in other games (with variations? like Monopoly pieces)
  • Stackable playing pieces (like Trouble)
  • Juggling balls - hollow, filled, solid
  • Juggling clubs - hollow, one-piece

  • Toy plates, cups, bowls, etc.
  • LEGO compatible spare parts
  • Tangram puzzle
  • Spiral drawing toy (a.k.a Spirograph) - older, fun toy. Some lo-res images.
  • a new kind of Wikipedia: gömböc. (Or is there only the one shape?). The world's first operational gömböc was made with additive 3D rapid prototyping technology.


Ornaments

Useful items

Simple household items

  • Plates
  • Cutlery (File:Fork.blend,File:Spoon.blend)
  • Protective cases (e.g. for phone, glasses)
  • Tupperware and other containers
  • Rulers
  • Bottles
  • Coat hanger
  • Rope
  • Vase
  • Clothes pin (just add spring)
  • Old-fashioned clothes pin (no spring necessary)
  • Ice tray
  • Coasters
  • Pretty display pieces for holiday parties
  • Measuring cups and spoons
  • Fly swatter
  • Letter opener
  • Pet dish (various sizes - with support for big dogs so they don't have to squat to eat/drink)
  • Sprouter
  • Salad tongs
  • Chopsticks
  • Comb
  • CD case
  • Bookends
  • ^Screwdriver
  • Coffee filter holder (problem with thermoplast?)
  • Pillbox -- rounded shapes so that people with arthritis can easily slide pills out of today's slot. Perhaps someday a smart pill box.

More complex / functional household items

Handy aids for the handicapped

  • Easy grip handles for toothbrush, keys, etc.

Educational items

Mathematical items

  • Platonic solids
  • 3D model of a function
  • Slide rules (can a RepRap use the gcode generated by "slide rule" software by Hugh Aguilar?)

Biological models

  • Skull / vertebra / hip joint (human)
  • Entire skeleton that can be wired together (human and various animals)
  • Inner ear anatomy
  • Animal tracks (various example animals)
  • Animal jaws (herbivore, carnivore, rodent, etc.)

Chemical models

  • Simple molecules
  • Enzyme (active site and substrate)
  • DNA helix

Physics models

  • Boomerang
  • Archimedes screw
  • 3D model of a 2D dipole scalar field
  • Mystery object (sphere with an internal structure to be probed non-destructively by students)

Metal

Several people have successfully fabricated metal parts indirectly, using FFF plastic parts to create a mold - see High Temperature Metal Casting and Casting/Pewter.

Some people are researching ways to fabricate metal parts more directly, with a metal deposition print head.

mechanical
  • ^gears and gearboxes of all sorts, large and small.
  • ^pistons for diesel, steam engine
  • ^ other expanders for engines
  • ^ leadscrews
  • ^ bolts, rivets, fasteners. Not so much to save money but because of the endless variety it would be nice to just print one when you need it rather than stock so many.
  • ^^ A wide range of almost arbitrarily shaped objects for everything from the chuck on a drill to the focusing assembly on a digital camera or parts for a lathe.
  • ^ drill bits in cobalt steel or HSS?

plastic

ceramic

mechanical

Multiple materials

  • ^ stepper motors
  • ^ Power motors, AC and DC.
  • ^ Some types of electrical components like resistors, capacitors (needs high resolution) transformers, connectors, wires.
  • ^ Printed circuit boards, especially ones with electrical components mentioned above already on them.
  • ^ Complete tools like an air drill etc. ready to use.
  • ^ A car or subassembly for a car. Axle etc.
  • a tire [1] for a car.
  • ^^A bicicle. Bicicles are objectively better than cars (socially and ecologically, obviously not in performance), and it would seem to be substancially easier to make.

Other materials

  • windows
