File, Knife, Big Needle
(1) print: & mount the
Ultimaker Generic HeadMount
with >=40% Fill
(2a) print: "Ultimaker-syringe_rings-lower.stl"
(2b) print: "Ultimaker-syringe_rings-upper.stl"
(2c) clean your parts and bore through the holes
(2d) push [2a] all the way onto the syringe from below - printbottom facing upwards
and rotate holes 90Â° relative to syringe fingergrips
(2e) push [2b] onto the syringe piston from above - printbottom facing upwards
and rotate 90Â° relative to thumbloop
(2f) more later
(3a) print: "Ultimaker-HeadMount_syringe100_v1.stl" with >=40% Fill
(3b) ziptie [3a] onto the bottommost part of the syringe
(3c) more later
(4a) print: "Ultimaker-RealBowdenDrive_windercoupling.stl" with >=80% Fill
(4b) print: "Ultimaker-RealBowdenDrive_winderspool.stl" with >=80% Fill *****
(4c) clean your parts and bore through the holes (3.0mm & 2.5mm)
(4d) Take the top M6 Nut from the big gear on the extruder -
put it into [2a] and screw the whole assembly back onto the bolt. (arrows should match gear arrow)
(4e) with the big needle thread the dyneema through one of the holes in the spool [4b]
(4f) thread the dyneema through the hole thats 90Â° crossing the previous one passing the dyneema on one side.
(4g) thread the dyneema back through the same hole passing the dyneema on the other side.
(4h) pull out a dyneema loop (as little as possible)
(4i) knot th dyneemas net onto that loop an cut it short (1to2mm)
(4j) pull the knot into the spool
(4k) perfect - later more (If anything is unclear look at the pictures at the Thingiverse site)
(5a) print (>30% fill) and mount
"Ultimaker BowdenFeeder Repair Kit"
The windercoupling will springclamp onto this!
No drilling is necessary! just stick it on
(5b) print: Ultimaker-RealBowdenDrive_windercoupling.stl
(5c) push the ball bearing into [5b]
(5d) slide a M3 nut into the sideward slot of [4b] (you may file it out first)
(5e) push [4b] into the bearing
(5f) fix [4b] onto the bearing using a M3 screw and the washer that was included in [5b]
(5g) let us call the result the "winch assembly"
(5h) thread you dyneema strand from [4b] in order through
[5g] - The long bowden tube -
one side of [2b] downward -
one side of [2a] downward -
The short bowden tube -
other side of [2a] upward -
other side of [2b] upward -
and make a knot there
(5i) friction stick or glue the ends of the bowden tubes into their corresponding pockets
(6a) push [4b] into [4a] and onto
push [5a] onto the filament drive
stick the syringe with its [3a] onto 
pull the syringes piston too its outermost position
tension the dyneema strand so there is only one or to windings on [4b]
make a knot on the other end on [2b]
(7) quickmounting: (within seconds)
pushpull [3a] onto  (lock with two M3 bolts if needed)
pushpull [5f] into [4a] and onto [5a]
Both are lockable with M3 screws
Test with dough:
Make the shortbread doughs viscosity barely self-supporting.
Skeinforge settings that I used for the dough test:
(These are for the naked 2mm diameter syringe tip.
For the 1mm diameter adapters halve the layer thicknss and
quarter the flowrate.)
Layer Thickness (mm): 1.25
Perimeter Width over Thickness (ratio): 1.8
Feed Rate (mm/s): 30.0
Flow RateSetting (float): 6.6
Extra shells: all 6
Infill Solidity (ratio): 0.0
Solid Surface Thickness (layers): 0
Don't mount the Syringe too high up or else the thermoplastic printhead might scratch through your extruded paste
