First upload. Simple clip-on style clamp for P3Steel's Y axis. May also possibly work on the Z axis, although that is not tested and also not applicable.
There are other designs of this type of clamp here on Thingiverse, but those use a screw and a nut, which my design does not. My design also only reduces Y travel by 2mm in total, whereas other designs reduce Y travel by 10mm+.
Just rotate it upright in your slicer, print, and clip on. You need 2 per smooth rod, 4 in total for the Y axis.
EDIT: this design is total shit and unprintable. Do not print this
I spent 10 min in Sketchup to make this.
