This 3D printed glock block should make taking your glock or polymer80 apart way easier. Been looking for one of these tools but couldn't justify what they were asking. Print it out and see if there are modifications that you might want me to make. There is no need to print this at more than 20% infill, but it is up to the user.

I uploaded a V5. What this did is increase the size of the holes and increase the amount of capture the frame would see. Original worked fine but I do like to make improvements. I also included a link to a video of the block being used.
2-25-18: I changed the file to have a water mark and only uploaded the STL. Found my designs on other sites for sale with no credit given. stp files will not be posted for products that I plan to sell any longer.
You will need to scale to 1000%, model built using Inventor.
