The Dental Chair Lever is a 3D printed replacement lever that compresses the lowering mechanism on a dental chair. It was developed as a fix for a broken lever on a dental chair at Nuwakot District Hospital, Nepal, where the original lever was unable to compress the lowering mechanism; this print holds two 2-rupee coins in position so they can compress the mechanism instead. It is 3D printed using ABS plastic filament.
Usage Notes
Print vertically so the part forms a U-shape on the print bed for maximum strength.
Field Ready develops manuals to support both the fabrication and safe use of its products. A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.
