Parametric universal spool holder - short Mod

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4780889.

This is yet another remix of the [Parametric universal spool holder] (https://www.thingiverse.com/thing:767317) - like this a lot, but I have some very narrow spools and also don't want to waste so much width in my Storage box. Also I made the middle rod holder a little bit wider so that my 8mm rod fits comfortably through and also made the fitting for the 608 beaing wider so that you could press it with Hand in the hole and don't have to heat it. Nevertheless it fits tight and don't fall out.

Update: For Sunlu Spools with big inner hole new version.
