At work I have a Fortus 250 and removing the ABS+ from the disposable print trays can be a lot of work if you don't have the right tool. That's why I made this thing. Just slide in a blade and remove any remnants from previous prints and reuse! Recycling is fun.
This thing is designed from scratch yet quite similar to one I printed awhile back:
...but I had to design my own so that it wouldn't use as much support material. The main difference between mine and mrcleanr's is that mine doesn't have a pleated handle-head connection. It's just flat until it comes up to the tapered edge near the blade.
Remember: print as-is, where is, with external support only.
If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
Or, better yet, please feel free to dump a bitcoin or two here:
... include a note to the effect of "Hi 3E8, thanks for the razor blade holder scraper thing... we saved xxx money per print because of it".
You're welcome! (in advance) :D
Also, feel free to peruse my other submissions which are almost as varied as they are many:
May 12th, 2017 update: Added Handle0pt1mm.stl for those with a much more precise printer (like one with .1mm resolution like the Fortus250 that I use). I've also included a screenshot of the suggested Support Settings for printing so you don't have to put it in the ol' acid bath for five days to disintegrate the material in the slot.
Don't let model material populate the blade insert!!
It takes FOREVER to eat that stuff away in the acid bath. Just use support from the base to the part. Print it oriented as-is and you'll be fine.
Hope you find it useful.
