i just fixed something please redownload it, if you havent printed it yet. I made my own endstop based on jedynaks design. it uses two bic pens for smooth rods eliminating any slop, also the m4 screw is supported on both ends so it wiggles less. this is still a work in progress so any suggestions are welcome.


2 20mm m3 screws
4 m3 washers
2 m3 nuts
1 long m4 screw
1 long spring that will fit over m4 screw, approximately 20 to 30mm long
1 m4 nut
2 bic pens.

make sure you use support material for the part that over hangs, it should be pretty easy to remove.

drill the holes for the bic pens in the main frame so they fit in snugly.
drill the endstop holder holes so it slides over the bic pens but with minimal slop.
install the m4 nut in the nut trap
put m4 screw through top hole in frame, then slide spring on, then place the endstop holder in.

i recommend sanding the angled faces so they are smooth. in reality those can probably be done away with but for now it will stay.
