This is a remix from the mentioned original CoBra by pseudo6626 to alow it to use it with the Stage I brace mod (https://www.thingiverse.com/thing:4375609) by 3DCanh.
I have redone the bracket file that pseudo6626 already posted to improve the mesh on the frustum cutout and to correct for a minimal missalignment of the hole for the leadscrews. Also I had Issues with his frustum version because my stock leadscrews could not properly mount to the bearing in the frustums, so I dropped the bearings down a little.
The installation is straight foreward and you can use the stock bolts. If you want to build the z-brace completely new you need the bottom brackets for Stage I from the thing-post by 3DCanh as linked above.
Have fun!
UPDATE --- 2021-01-28 ---
Added a tensioner system to prevent the frustums from wandering upwards on the leadscrews. There are two variants:
1) Spring loaded type (uses a weak* spring of at least 16mm length and 7 mm inner diameter) - only works for the Stage 1 z-brace remix
2) rubber band type (uses two rubberbands per bracket/frustum) - works with the original cobra design aswell as the Stage 1 z-brace remix, BUT you need the remixed frustums!
*: the spring should only be very lightly compressed or even better installed with a slight airgap between the end of the spring and the bracket to prevent overconstraining the leadscrew!
