Extendable wheel chair ramp.

thingiverse

This is an extendable wheelchair ramp designed for door frames, measuring 18mm in height and 140 x 140mm in width. To extend it, simply insert the provided key into the bottom slot, connecting two pieces together with a smooth motion. The innovative design allows users to push the key inward, effortlessly linking multiple units as needed. I created this solution because conventional ramps are often prohibitively expensive - a single piece measuring 140 x 280mm can cost as much as $79. With this extendable ramp, individuals can enjoy greater mobility and flexibility at a fraction of the original price. Updated on February 7th, 2017, I redesigned the plate to accommodate two legs, enabling users to secure the ramp in place using double-sided tape. This modification ensures that the ramp remains stable and won't shift or move during use.
