1 1/4 inch grid

This roller aims to create a 1 1/4-inch grid pattern for XPS foam or a similar material.
The edges should cut a 2mm groove.
Roller5 is the 5 tile length roller (about 6 1/4 inches or 15.8 cm), and the Roller6 is 7 1/2 inches or 19 cm.

This is currently untested, I have been about to print similar rollers without supports. However, use your own judgment.

Update: 31/10/2018;
I've added two more 5 square wide rollers. The ModS is slightly smaller and the ModL is slightly larger by about 1/8 of an inch.

Updated 3/11/18;
I've added a file, 1_25in-grid_D__Roller.stl is designed to deal with the slippage that Roak pointed out to me. And remove the other files as the rollers will have created a distored grid.
