I made this goofy KA-BAR knife design, but I like practical prints. So I figured I'd put bed scraper on the end of it. Full Tang construction. It fits with a bit of friction but I recommend CV glue. I printed everything with 6 top and bottom layers and 3 parameters. For the blade I recommend 60% infill. You want it pretty ridged for sticky prints. The handle can be less like 10-15% but I recommend aligning the seems. I posted my sliced files for the MK3s+. Post your makes. Use wild colors. Happy Printing.
I printed the blade and handle using Fremover PLA+ and Inland PLA Pro respectively. I designed it for a easy fit. If you have issue just use a steel knife blade and scrap perpendicularly against the four corners of the pla blade's tang. Shave off a bit and try fitting again. This did the trick for me.
If you like the KA-BAR see the below link for a Toy/Toothpaste squeezer I also made.
