New Ruler 150 That Stays Put When Pressed

For (With Whom)

People with hemiplegia or similar conditions who find it difficult to keep an existing ruler fixed with one hand while drawing a line with a writing tool in the other, but who want to try two-handed use as much as possible.

Why

How

Created with inspiration from the "Ruler That Doesn't Move on Paper When Pressed." For more stable fixation, it uses non-slip stickers. The area where the sticker is 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 sticker. Use the template to cut out the non-slip sticker and stick it onto the half-moon-shaped area on the back of the body. This model has a total length of 150 mm. There is also a 250 mm model.

▪️Notes Print with the top of the ruler (the side with the oval mark) on the bed. It can be printed without supports. Use the cutSupport part to cut the non-slip sheet and stick it onto the crescent-shaped area on the bottom of the body. If the non-slip sheet is thick, the feel of use may differ.
