Linear guide for SBR20

Linear guide created from the need of the economy. After some mechanical studies of the piece of aluminum I realized that it was a support for the guide that is fastened with a screw behind. As the grip is not so strong then we will have the same product.

One is with pin that centralizes the assembly, plus there is a file without the pin as well.
The spacings between the holes to hold the shaft is 150mm and I designed to use M6 bolt.
There is no recess on the opposite side of the guide because the idea is to use a through screw that will secure the table.

The total height including the pin is 190mm and should be printed on a printer with high height.
