Tobis Shield (Corona Covid19 Face Shield for Laser Cutter)

thingiverse

This is a lasercut face shield inspired by the famous Prusa 3D-printed face shield design. It combines comfort with fast production times. It consists of two head bands cut from 0.5mm PETG or PA, a "sunshade" cut from 3mm Acrylic, two hooks for the elastic band, a Buttonhole Elastic Band 15-20mm wide and 6 hollow rivets with 4-4.3mm outer diameter. For the transparent part, see below. To assemble, you will need a hollow rivet tool; I recommend this approach for mass production. Alternatively, you can also use brass fasteners for packaging, which require no tools for assembly. ## There are three flavors available, depending on the transparent material used: • ISO: one for shields made with a 4-hole (6mm holes, 80mm apart, ISO-Standard) hole punch for DINA4 sheet material or prepunched off-the-shelf material. • US: one for 3-hole (108mm) for the imperial crowd. • (Coming soon) Prusa: one for the Prusa-compatible shields which are 24cm x 24cm in dimension. If you want to make the transparent part of the face shield yourself, just use DINA4 or LETTER transparent sheets and make holes with a hole stamp. You can find a cutting template for the Prusa-compatible at https://prusa3d.com/downloads/others/COVID19_SHIELD_FOIL.pdf ## There are several files available for each flavor (EU, US, Prusa, see above): • The starting point is the V2_Tobis_Shield_XXX_XX_All_Parts.pdf/.dxf. There you will find every part in one file. • V2_Tobis_Shield_XXX_XX_Instructions.pdf: Assembly instructions. ## If you want to start mass production, there are already nested files available: For Lasercutter with 450mmx30mm cutting area (e.g. Trotec Rayjet): • V2_Tobis_Shield_XXX_XX_05mm_longband_nested.pdf/.dxf for the long headbands for 0.5mm material (eg. PETG or PA). • V2_Tobis_Shield_XXX_XX_05mm_shortband_nested.pdf/.dxf for the short headbands for 0.5mm material (eg. PETG or PA). • V2_Tobis_Shield_XXX_XX_30mm_nested.pdf/.dxf for the sunshade and the elastic band hooks for 3mm material (eg. Acrylic/PMMA). • (Coming soon) V1_Tobis_Shield_XXX_XX_massproduction.pdf: Assembly instructions and tips for mass production. ## Version History: Version 1 (V1): Initial Release Version 2 (V2): It's now possible to make it without rivets, just staples and brads. Also shape edited for better nesting. Added US version.
