Bowdabra-like Bow Maker

Print one base, one ruler (if desired), one fly - to push the bow material together, one end cap, 2 BladeUR-LL, 2 BladeUL-LR and assemble.  Print in the orientation shown in the 3MF file.  Use 4-M3x10 screws to hold everything together and 2 medium rubber bands to make the blades come together. The endcap fits VERY tight - a touch of light sand paper or removing some material with a hobby knife may be necessary - depends on how bad your printer "elephant foots" the first layer.  Put the rubber bands in the channels in the bottom of the blades and insert into the base - align the chamfers so the very middle looks like an X with all four blades installed.  Install the end cap and secure with 2 screws, then push the blades tight against the end cap and install one screw in each to secure them.  I printed the ruler plate in white and used a Sharpie to make the numbers and marks stand out (still haven't upgraded to multi-material)
