Geeetech i3 replacement x axis ends

I recently had to replace my x ends on my i3b, downloaded a set and found then to be to narrow (21mm rod & thread rod distance), so decided to create my own, hope they are useful.
Just added a further 2 variations of end stop mount, so now the endstop can go front, back and below depending on needs.
the x end stop is designed to house a mini micro switch 13mm x 6mm
other items required are :-
m4 nut
m4 bolt 30mm (preferably hex dome cap screw)
m3 lock nut
m3 bolt 20mm
gt2 idler pulley g
