This video from @JerryRigEverything shows how a self-propelled toddler-sized manual wheelchair, designed by MakeGood, is 3D printed. This particular example, which included printing the tires in segments, took about 200 hours of printing time.
Carmela Chillery-Watson became the youngest-ever recipient of the Member of the Order of the British Empire medal last December, when she was honored for her prodigious fundraising work at age 11.
In this video, a much younger Carmela, who has LMNA congenital muscular dystrophy, expertly appraises the ramp of an accessible taxi and drives her power wheelchair aboard like a pro.
