After I bought TL smoothers and wanted to mount them to my printer, i found out that there is no design like this yet..
So I took measurements from this design: https://www.thingiverse.com/thing:2839586 by user called printaway, thanks for that!
After all the designing, I´ve printed first prototype and it worked!
Here are screws used to screw mount onto the extrusions...:
3x M5x10
3x M5x12
6x M5 squared nuts
To mount rest of the parts like arduino, mosfet,.. I used M3 and M2,5 screws (and nuts) of random length...
NOTE: Smoothers are held by precise size, it may seem like bad way, but it actually works really great... also connectors secure them in place... if you want you can print cover for them from printaway desing, it should works because sizes are the same...
In files section you can find 5 files, one is major one which contains whole mount (can be printed only on big-size beds) and then you´ll find there 4 parts of mount which can be printed separated and glued together with acetone / super glue / second glue.
