This is a remix of the EZ-Snap Razor Blade Handle by AdanA. It has been adapted for classic double-edged (Gillette) safety razor blades. These are only 0.1mm thick and slip under prints very easily. You won't be able to lift any prints with such a blade except very small ones, but you can use the clearance to shove a thicker and larger blade or plastic sheet under the print, and easily remove it from the platform. This also works very well to remove skirts and any other small bits stuck to the platform. Just be careful to keep the blade at a low angle to avoid digging it into softer build surfaces like BuildTak.

Update 2016/08/07: uploaded version 2 of the model, which has a larger tab that offers a more secure mount for the blade, allowing to push harder on the blade without bending it.
Update 2016/10/05: uploaded version 3 of the model, which has an even larger tab and also a slightly taller structure to hold the blade in place. This version has less risk of the blade slipping out when it gets caught under a print. (I kept v2 available for those who prefer the extra bit of flexibility in the razor blade.)

I recommend printing this at 0.1mm layer height to ensure that the subtle recess that prevents the blade from moving around, comes out right, and the tab to secure the blade will fit correctly. If the tab would be too loose, add sheets of adhesive tape to its underside until it is snug.
An optional cap is included (you can print this at any reasonable layer height).

Of course: be careful especially while mounting the blade, those blades are very sharp. I recommend using the edge of a table to push the tab in the slot, so you don't need to come near it with your fingers.

Printed it, but the small part came too big for me. Although, I did not yet done a calibration, so my printer might increase the size of things. But the handle part should have been increased as well.

I should try printing it again in a higher quality.

I ran into the same issue. I printed the thing out and the small part turned out to be to big to fit the big one
