New) Press-to-Hold Ruler 250 That Doesn't Move on Paper

For (With Whom)

People with hemiplegia or similar conditions who find it difficult to keep holding an existing ruler with one hand while drawing a line with a writing tool in the other, but who want to attempt the task with both hands as much as possible.

Why

How

This was created with inspiration from the "Press-to-Hold Ruler That Doesn't Move on Paper." To get more stable fixation, it uses non-slip stickers. The area where the stickers are applied is limited so that it grips when "ON" and does not grip when "OFF." The half-moon-shaped 3D model is a "template" for cutting out the non-slip stickers. Cut out the non-slip sticker using the template and attach it to the half-moon-shaped area on the underside of the body. This model has a total length of 250mm. A model with a total length of 150mm is also available.
