Table leg stilts
My chair didn't fit beneath my desk so I drew these up quickly in SketchUp. Adds 37mm in height. The stilt's total height is 40mm and the base is 73mmx73mm. Nothing fancy. Appropriate for ~32mm or ~40.5mm square legs. Includes a recess so that a moderately centered non-marking plastic nail "glide" can fit without needing removal. SketchUp file is included in the thing files if you want to remix or modify.
Update 2018.12.22 - Added a version for larger table legs (that I'm going to use on for my dining table). The part names indicate the leg opening size (e.g. 36mm^2 opening for ~32mm^2 legs, etc.)
