Description
This is designed to be a speed print variant similar to Mojo's Speedprint remix of the Prusa RC2 but with a shield fit closer to RC1. The main reason I modeled my own from scratch was to create a CAD file that others can readily modify to meet their needs.
The CAD model was made to facilitate easy modification and tweaking of dimensions. At the moment, it is optimized for Letter-sized plastic with 7mm holes space 4.25" apart, the de facto standard in USA and Canada. The CAD model utilizes variables and equations to aid tweaking dimensions as needed. For example, by changing the VisorHoleCount variable, one can automatically change the model to accommodate 4 holes instead of 3. Changing the VisorEndHoleSpacing variable from 215.9mm (8.5" for USA and Canada standard triple hole) allows you to adjust the spacing of the end holes.
Print Dimensions: 147x185mm (5.8"x7.3")

Materials and methods
Material: PLA though any rigid material should work.
Use: Single use
Shield Assembly: Many thin plastic sheets, lamination sheets, or even transparencies should work. The above STL is designed for letter sized paper with 4.25" triple hole spacing, the standard for the USA and Canada. My hole puncher is an ACCO 20 that produces ~7mm holes in the plastic. If your holes are larger or smaller, use the Onshape file to modify the dimensions to suit your needs.

Comments
ChiRag Chaudhari commented agoThank you so much your design.
It is making difference in Champaign-Urbana community.
If possible can you please add one more tab on both ends to hold the corners of the sheet in place. I think it will help sheet from flopping.
One again thanks for the design. I have been printing them non stop.
