Awesome idea! But ran into an issue: printed out the 3.5" but it doesn't fit my Wahl brand trimmer. Pictures attached (blue clipper is the 3D print, yellow clipper is one that came with the trimmer and fits). Second picture shows how the 3D printed clipper is too short to click/latch securely onto the trimmer blade. If you could let me know how to fix this problem, that would be great! Looking forward to hearing from you, thanks!
