Razor blade holder (for microscoping)

A holder for razor blades for use in preparing samples for microscoping. After visiting the botanical course that was part of my biology course at university i created this holder for the razor blades we use to cutting our samples for microscoping to protect me from cutting myself and allow better grip when cutting hard plant parts. I designed it to hold the standard blades with straight edges and the typical groove in the middle. I printed mine in standard PLA and they hold up quite well, the long bridge in the back prints good enough to not need any post processing. To insert the blade just lay it in on an angle behind the bar in the middle and carefully push it in, to remove it just push the blade up and pull it out.
