Simple design to stabilize the aluminium i3 frame that's not too fussy about the angle and easy to retrofit (just replace the rear threaded bars with longer ones)

Instructions

I've found I've been seeing quite a lot of wobble on my aluminium plate i3 when printing. This is partly down to me printing on a wobbly table and partly due to mounting the spool on the top. So to rectify this I've made these parts which allowed me to retrofit stabilizers to the plate making everything so much sturdier.

I didn't know the exact angle of the plate so I've created the parts to be flexible enough to fit anywhere from 15 degrees to 35 degrees - the median point being the rough measurement of 25 degrees which I'd measured in my setup (having just checked the actual angle turned out to be 20 degrees.

There are many similar designs but none that I saw had the flexibility I wanted from my design.

Enjoy.
