This is a 130% remix of BobDavis's wire clip (https://www.thingiverse.com/thing:1854540). I found his clip too small for the 20x20 aluminuim profile of my Creality CR-10 printer.
In this size it fits well.
Hictop 3DP-20 / Creality CR-10
Added 30mm & 50mm clips
I thought it would be a good idea to add longer clips for more stability.
These were added today (24th september 2017).
Ofcourse this can be done in the slicer. That is how I did it.
So if you need custom sizes; pick the smallest of the three clips and just resize the Z-axis to the desired height.
