Version 2 of my orginal razor scraper here: http://www.thingiverse.com/thing:249012

This one is two piece, requiring you to glue the razor scraper to the handle. I made it this way so that when you print it you dont have to clean out the slot making it much more easier to insert the blade. Also its much more stronger then the original. I had requests for blade cover, so I've included one. Its a tight fitting lid, sand it to your liking if desired. For the lid hinge, I used a piece of 1.75mm filament. You can use whatever(coat hanger, metal rod, etc).

Printed mine using the low defaults on my Rep 2x:

For both parts I suggest: Infill = 33%
Shells = 2
Layer Height = 0.30mm

Make sure you print the scraper head vertical like shown in the picture. Also make sure you super glue the scraper head to the handle using a liberal amount of glue. Enjoy!

The handle was printed with supports on. The rest of the parts shouldnt need it. I didnt use rafts for anything.
