Mass-Producible 3D-Printed Face Shield

This Project is Based on the Following Design: https://thingiverse.com/thing:4233193 Loading .3mf-Files into Cura Can Take Some Time, Even Minutes. Simply Drag 'n' Drop the File and Leave It for Some Time. This Process Also Uses Significant RAM, Causing the Loading Bar at the Bottom of the Screen to Disappear After a While, but Cura Still Loads in the Background. I Have Created a Mass-Producible Face-Shield That Is Lightweight, Compact, and Robust. To Produce One Face-Shield, You Will Need 1 A4 Acrylic Sheet and 1 Elastic Band. For Ender 3, Ultimaker 2, and Ultimaker 3 Printers, Pre-Configured GCODEs Are Available for Direct Printing. For Other Printers or Larger Quantities, You May Need to Modify the Cura Settings. The Design Is Optimized for Use with Cura, but It Has Not Been Tested with Other Slicers. The File "10 x Face-Shields (Stacked).3mf" Contains 10 Already Stacked Face-Shields, Including All Required Parts. If You Want to Produce Fewer Than 10, Simply Load the File into Cura, Hold Down CTRL and Right-Click on the Items You Wish to Remove, Then Press DEL to Delete Them. After That, Check the Settings in Cura (Under Print Settings) and Slice the Model. Info About Ready-to-Print GCODEs: * 10x for Ender 3: Optimized - 1 Day, 5 Hours, 31 Minutes, 260g * 10x for Ultimaker 2: Default - 23 Hours, 25 Minutes, 260g * 10x for Ultimaker 3: Default - 1 Day, 10 Hours, 15 Minutes, 267g Arrange Models By Yourself (or Problem with .3mf-File Loading) If You Experience Issues Opening the .3mf File Containing 10 Face-Shields, It May Be Due to Insufficient RAM on Your PC. In This Case, You Will Need to Arrange the Models Individually. To Do This, Load in the 3 STL-Files and Multiply Them as Often as You Want to Print Them at Once. Next, Group All "Shield_Hold.stl" Models Together by Holding Down Shift and Selecting All with a Left-Click. Then Right-Click and "Group Models." Place the "Shield_Hold.stl" on Top of Each Other, Ensuring the First Model's Z-Position Is 0, the Second Is 10.6, the Third Is 21.2, and So On. There Should Be a Gap of 0.6 mm Between Two Shield-Holds, with Equal X- and Y-Positions for All Models to Ensure They Are Aligned. The Other Models ("Clip.stl" and "Face_Onlay.stl") Can Be Placed Wherever You Want. Important: Check the Correct Rotation of Each Part, as They May Not Be Rotated Properly!

Slicing and Loading of the File Can Take Some Time.
