I wanted to create a pen holder that helps people with disabilities hold and use a pen. This tool will hopefully help those with motor movement / dexterity difficulties gain a better grip of an everyday pen, allowing them to put their energy into writing and less into holding the pen!
This tool has been designed so that you can have the pen angled inward or outward. When inserting a pen, use a twisting motion to stop pen from coming out.
If you need to use supports then I would recommend filing / sanding.
