  <p>Surgical rubber tubing is inexpensive and available in several thicknesses, so you can regulate the stiffness of the shock absorber. Just make sure that its internal diameter is 5mm so it fits around a technic axle.</p>
  <p>An example assembly would be a 6-stud-long technic axle plus an angled technic connector, a bush, and a 1x1 brick with technic hole:</p>

  <p>...then cut two lengths of rubber tubing and place them above and below the 1x1 brick.</p>

  <p>If you <em>really</em> want to use rubber bands, then you can leverage parts 32039 (angled axle connector) and 27940 (3L bar with perpendicular pin hole) to add symmetrical rubber bands, like so:</p>

Body: <p>I have tried making a custom shock absorber, but every option I see uses springs or is too bulky. Is there any way to make a custom LEGO shock absorber using rubber bands? I'm thinking of 6x1 studs with medium stiffness.</p>

  6 as the overall length is quite restrictive, but something like this could be adapted to work if sandwiched between other parts that restrict non-axial movements:

  The length of the black pieces would have to be negative if the total length needs to be 6, but if the symmetric assemblies can be put besides each other (thus violating the 1 module diameter constraint), then by using 4x1 plates you'd get 2 travel length.
