I've been looking on Thingiverse and would like to make a new spool holder to facilitate filament changes. There are two basic kinds: the ones that are similar to the holder that comes with the Prusa Mk2S where the spool is held through the middle, and the ones that provide a bottom on support, similar to the following: https://www.thingiverse.com/thing:2362427
I'd like to make one similar to the second one linked above, where the spool is placed on the rolling supports and has nothing through the middle. However, my concern is this: if there is a kink or jam in the filament such that it no longer comes off the spool, or is otherwise held up on the spool, could the extruder pull the spool off the holder, such that it rolls off into the front and comes crashing down onto the extruder or print bed? Or am I just being overly cautious?
I'd love to hear from others who have printed/used this style of spool holder and their experiences.
Thanks very much in advance!
PS - My printer is an Original Prusa i3 Mk2S, with less than 4 days total print time on it. Just got it in December and love it.
