D-bot Spool Holder Arm for 2020 extrusion

thingiverse

I needed a spool holder for my D-bot printer. This is a remix of thing: https://www.thingiverse.com/thing:2938086 My compliments to Elektrolenin for his well thought out design. I shortened the holder, rotated the mount 180 degrees, and added space to the base of the arm to provide the clearance I needed. After printing the original, I found that the piece that inserts into the groove was a bit too wide so I reduced the width of the insert. I also recessed a space for the nut so that after it snapped into place, the nut could be inserted into the 2020 extrusion. Finally, I removed 5mm from each side so that I could print it on its side without supports.
