Liked the model from @HandsomePotato but needed one which fits on my 4040 Extrusions, so removed the drillholes and made them linear. The "handsome" holder has the perfect width to fit onto 4040 extrusions.
@STRONGER Version: my first normal remix broke in the third paperroll fight (used ABSx), so this model needed definitly some adaptions and here it is.
additive printsettings: you could use some modifiers with high infill (80% or 100%) in the fragile zones.
The tip and the connector you can find here:
The author remixed this model.
made it stronger on the Base incl. the angulation because the design have been to weak with ABS when pulling strong on the paperroll.
