Paper Holder
thingiverse
My wife uses a paper holder similar to this at her workplace and she couldn't find any, so after some trial and error, I was able to create something for her that would work perfectly. If you need to hold a piece of paper up while typing, this solution may be exactly what you're looking for. As always, if you have any questions, concerns, or comments please let me know in the comments section below. Edit 3/3/2019: I added the original 123D design file as well as the new Fusion 360 file. Since I haven't tested the new design yet, let me know if there are any problems with it.
With this file you will be able to print Paper Holder with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Paper Holder.
