Support for Anycubic I3 Mega Spool holder

thingiverse

This is an additional upgrade for the Anycubic I3 Mega spool holder:\r\n\r\n* https://www.thingiverse.com/thing:2734209\r\n* https://www.thingiverse.com/thing:2647030\r\n\r\nI was not pleased with the laser cut acrylic spool holder originally packaged with the I3 Mega, so space constraints were not the only reason I decided to print a new holder.\r\n\r\nMy printer sits in a closed cupboard reaching an ambient temperature of about 45°C during printing - which may have caused the spool holder to sag due to its weight.\r\n\r\nSince my printed piece was still working perfectly, I created a support for it to hold up against the weight. This new part can simply be added to the existing design.\r\n\r\nThe STL provided here fits for me when the spool holder is at the lowest position of the Z-bar. See the pictures for details on how to attach it.\r\n\r\nIf your spool holder is mounted higher, you can edit the OpenSCAD file by changing `base_height_from_center` to your desired height - this length goes from ground to the center of the cylinder holding the spool.\r\n\r\nYou might notice in the pictures that I added some felt to the bottom of the support. This was a fix for my first print, which came out too short, so I just attached it like that. The STL provided has been corrected by adding 2mm in height.
