A customisable book opener / page holder generator that produces page holders from SVG or DXF files. SVG files shoild be a simple filled outline, or a filled pattern outline.

A number of SVG files are included for use as templates. SVG files must be in the same folder as the SCAD file. You can use your own SVG by naming the file as 'default.svg' and adding it to the folder. I've also included the .json file for example designs and included a number of STL examples.

You can customise the following:

• Independently scale x and y axes, or force a constrained scale
• Set the thickness
• Choose where you place the thumbhole by adjusting the x/y axis offsets
• Flatten the hole to an oval shape if desired
• Use a rotating sleeve in the thumb hole instead of using a plain hole
• Add an extra sleeve around the thumb hole (and sleeve) if you use a design that uses a hollowed center or an internal pattern
• Change the colour of the sleeves to help with ofsetting the location during design
• Preview a cross-section during design to check clearances
