This easy to print paper holder can hold A4 and A3 paper in landscape or portrait.
It can be placed directly onto the desk or it can be clipped on to your laptop / tablet when desk space is limited.
It can be used for many applications such as holding
Engineering drawings / design
Recipes in the kitchen
Data input / reports
Simply clip the paper first then slide onto your laptop / tablet the spring action will automatically grip the paper more firmly. To remove slide off and unclip.
I have included 3 different sizes depending on the thickness of your laptop up to 12mm thick (1/2 inch)
Also included is the OpenScad file so you can customise your own.
The stand is optional but gives more stability for table top use, a must for A3 size paper
The stand is not required for attaching to laptop.

Change parameters to suit your application

Press F6 to render then save STL file for printing.
Typical parameters that worked for me
Alter_spring_gap=4;//0 to 7 (7 = the smallest gap about 5mm and 0 = larger gap about 12mm see attached picture)
paper_gap=0.2; Depends how your printer prints small gaps without fusing together
thickness=20; I recommend not less than 20
grip_radius=13; If this is too big it will not hold the paper in the upright position
