I HIGHLY recommend trying the updated blade design first, it's posted as a remix of the blade design here: https://makerworld.com/en/models/1117243#profileId-1114985

I may be old skool, but I hate the idea of a metal scraper blade anywhere near my print bed. I have also had really good luck with PLA printed scrapers getting up the edges of my print. Unfortunately they are not long lasting at all and even with some fantastic lightweight printable scrapers in the community, I hate throwing the whole handle away after just a dozen prints or so..

And so I present the best of both worlds! This tiny blade works with the well known (and reusable!) Bambu Lab scraper handle (https://makerworld.com/en/models/12702?from=search#profileId-12703) which means you don't need to toss the whole thing in the garbage when the blade gets one too many nicks in it. Each blade also prints in just over 3 minutes (without accounting for heating/leveling time) and they are low profile enough to print object by object, so you can pack a build plate with them and knock out a few dozen to keep on hand quick. Admittedly these are not super strong… But you can easily make up for that with sheer numbers!

You can even pack like 59 of them on a build plate with room to print object by object, which is a great way to run out your dwindling spool… Just under 3hrs for the batch and 46.06g of filament.
