This is a poor mans Z stabilizer bar kit. I had extra screws and bits laying around, which turned out to be
Two (2) 2 1/4" x 3/8" screws,
Two (2) 1/2" x 1/8" Self Tapping Screws
22" of 1/2" ID steel rod.
That's what this kit is designed around.
I printed this at about 75% infill in Hatchbox PLA, and it has been working just fine.
Print 4 of the nuts, 2 of the posts, and 1 of each bracket.
The brackets have 4mm holes in them to accompany screws to attach to the frame.
Print the following
1x Top Bracket
1x Bottom Bracket
2x Connecting Rods
4x End Nuts
YOU WILL NEED A DRILL
You will need several screws, 4 to connect to the frame, 2 to connect the metal rod to the connecting post, and 2 to hold the brackets (one each for top and bottom).
You will need 22" of 1/2" ID Pipe. I picked mine from an old floor lamp.
1) Drill a small hole about 1" from each end of the pipe, only drill through one side. Use as vice to keep the pipe stable if you have one handy.
2) Insert connecting rod and set aside.
3) Attach upper bracket to corner of printer frame. Keep as far to the side as possible.
4) Attach angled lower bracket to bottom corner of printer.
5) Drill out nuts to appropriate diameter for your screw, I had to go up slightly from what was printed. Test the screw race by turning the screw through the nut. Once you have a successful fit on all four nuts, move on.
6) Insert bar with fittings in between the brackets.
7) Insert screw into rounded end of nut and then into bracket and rod, then into flat side of second nut.
8) Once both top and bottom brackets are secured, screw in the center bar with small screws into the holes we made in the beginning.
9) Once center bar and rods are secure, tighten all nuts to secure brackets. You can use a business card as a shim if necessary.
10) You are done!
