Heyho :)Here is part 3/3 of my DIY projector screen project.A practical fastener for the screen (or other thinner objects).It works quite simply and is very strong.FunctionInstallation: Simply place the two parts under and over the piece to be tensioned and fasten the Screw.For the M3 Version you will need a M3 x 10 mm Screw and a M3 Nut (Standard or Nylock)Don't be afraid to tighten the clamp up quite hard! :)Design FeaturesStrong teeth: I have tested many prototypes with different raised teeth. This design worked the most reliably. The teeth bite deeply without damaging the canvas and distribute the force relatively evenly.Strong Geometry: I designed the parts in such a way that they can be made as stable as possible with the FDM printing process and yet are easy to print. SkalabilitySince all parts are 3D printed you can scale the clamps up/ down as you like. Simply make sure to use more perimeter if scaled up. That provides more strength! So if you have a bigger rope you can simply customize this design for your needs.Also make sure that the Form for the nuts need to fit accordingly to your hardware!Parts ExplanationI used the M3 tensioner Jaw for my Project with a 5 mm Diameter Rope.There are 2 different Versions.Standard (to give the rope the least amount of friction)Vertical (My first iteration. Maybe interesting for some of you? :D)Material ChoiceIf the clamps are under tension for a longer period of time I would highly recommend not to use materials that can deform over time (like PLA). I used PETG for my project. Printing InstructionsSupports: If you optimized bridging you will not need supports. Else I had good results with some tree supports under the overhang area.Perimeter: I used 4 PerimeterInfill: I used 100% infill. But sth. like 40% should work too.Layer height: I used 0,2 mm with PETG. That works fine :)For best layer Adhesion I recommend to print a temp tower in advance and destroy it to check your best settings!If you like my work and would like to support me so that I can continue to invest a lot of work in free designs, I would be grateful for any small donation.Design 1 of 3: Tensioner1 Wedge:https://www.printables.com/model/723184-wedge-tensioner-clamp-for-canvas-tarpaulin-clothDesign 2 of 3: Strong Wall Mounting:https://www.printables.com/model/712980-extra-strong-wall-mounting
