Bat Shirt Cuff

thingiverse

An bat shirt cuff easy to print with a single-extruder 3D printer. The bat's wingspan is 30 mm. Inspired by https://www.thingiverse.com/thing:890483 but different solution. ==================================================================== Update 24 May 2022: I added a 1/2 extrusion width recess along the edge, allowing you to print the first layer at rich extrusion, resulting in an even front surface while avoiding an "elephant foot" (accidental brim). The printer will fill the recess. The recess is assuming an extrusion width and layer height according to my specification below. If you deviate significantly from this you may have to adapt the respective parameters in the source file and re-render. I slightly enlarged the holder in order to fit shirts with thick sleeves. Update 23 May 2022: I adapted the OpenSCAD source file to facilitate the use of alternative figure files in place of the enclosed "bat.svg": - The new figure must be in SVG (Scalable Vector Graphics) format (filename ending in ".svg"). Pixel file formats (".jpg", ".png", ".bmp" etc.) will not work. You will find online file format converters in the Internet, e.g. https://convertio.co - Download and install openscad.exe from https://www.openscad.org - Launch openscad.exe and open the .scad source file (File/Open). - Adapt the "filename" parameter. - Center the figure by adapting the x- and y-coordinates of the "xy_position" parameter. Verify by previewing (Design/Preview). - Scale the figure to the desired size by adapting the x- and y-coordinates of the "xy_scale" parameter. Verify by previewing (Design/Preview). - Move the holder bar further away from the cuff by adapting the "y_holder_bar" parameter (if required). - Render (Design/Render), export (File/Export/Export as STL), slice and print ==================================================================== How to create the bat shirt cuff: - Print the bat and the holder bar in black PLA. The eyes will be manually inserted, not printed. - Calibrate the eye holes with a 1.7 mm drill and insert two pieces of white 1.75 mm filament. Alternatively, glow-in-the-dark filament may add to the thrill. You may need pliers to insert the filament in a turning motion. At 1.7 mm bore the filament should stay in place by pure friction. - Calibrate the hole in the holder bar with a drill to something between 1.8 and 2 mm (depending on your available drills). - Calibrate the holes in the fork with a drill to 1.7 mm. - Position the holder bar between the fork arms and insert a piece of 1.75 mm filament as axle. You may have to secure the axle to the fork with glue, e.g. with superglue or Revell Contacta PROFESSIONAL. - Enjoy! The bat contour originates from <a href="https://de.vecteezy.com/gratis-vektor/fledermaus">Fledermaus Vektoren von Vecteezy</a> I added the eyes. As always I include the OpenSCAD source code for you to adapt and improve. Visit my other designs at https://www.thingiverse.com/thinger13/designs
