EZ-Snap Razor Blade Handle by AdanA Nov 14, 2012

Description

An evolution of emmett's razor blade handle.

Excellent for removing prints from the build platform.

-tweaked the fit to work with the single-edged razor blades I'm most familiar with (Stanley #9?). Key to a forgiving fit was the full cutaway under the corners.

-added unnecessary but fun flourishes like radii and chamfers

This is by far my favorite scraper design, as it can be used without any cleanup off the printer. However, to do that, I have to scale it up by 2.5% to account for some tolerancing. Otherwise, works like a charm!
I created a magnetic "cover" for this.

I've printed a few and I'm really struggling with the corner cutaway. It seems I always either cut it too thin or too think. Any suggestions?

Instructions

I printed at 0.123mm/layer, which gives an even multiple for the bottom sheet feature. I don't know if it's critical.

I've printed versions at 32% and 50%. 32% seems plenty strong.

If necessary, X-acto trim under the corner overhang details. I found that, by rotating it to the 45° position in which you see it here, I got much cleaner bridges there and trimming was unnecessary.

Consider filing/sanding the blade corners to reduce digging into the HBP cover (Kapton, etc.).

Consider dulling the blade ever-so-slightly. I've found that the first blade I had in the Emmet version of this works much better than new ones I tried in my updated model. New blades will just dive down into the Kapton if your holding angle isn't perfect. Presumably the only difference is time-related dulling.

Please do not try to force the fit - you may slip and cut yourself, or the blade may snap and harm your eyeballs or other sensitive things.

Great thing works and prints well. What would finish it off would be a cover to make storage with the blade safe.
Yeah, I was toying with the idea of making a pocket safe version... but have yet to get around to it :-)
This came out really cute thank you for the file :)
You're welcome! I'm glad it turned out well. I've really enjoyed using the ones I printed... though I can't believe it's been ten months since I first posted it. Time flies.
