wanhao duplicator i3 alternative spool mount.

SummaryI just dont like the stock spool holder. even though its metal it is still weak.. i find it sagging as soon as i put on a roll of filament. here is an alternative to the stock holder. (much stiffer) also has a hole for a lockdown screw so once you slide it on the frame you can lock it in place with a M3-.5x 16mm or longer. socket cap screw.. (might want to put a piece of tape where the screw contacts . it can leave a circular scratch from the screw in the paint.)Instructionsin cura. 0.2mm layer height 2mm shell thickness 1mm top and bottom thickness 15% overlap infill grid infill
