A spool mount that sits on the top of an aluminium plate Prusa i3


Print two plate mounts and two spool mounts. Cut 2 identical length M6 threaded rods and fit to each, with nuts and bolts, a plate mount and a spool mount. Cut a length of M8 threaded rod to carry your filament spool (with spool adapters - http://www.thingiverse.com/thing:60723 ) and press fit it into the spool mounts.

This does add some weight to the aluminium plate and does make the frame bend backwards. This may affect prints but I am still testing that.

Check back to www.sub-design.co.uk/i3build/ to see how that pans out.

Ooops! Missed an STL - had two copies of the scad file for the spool mount. Added STL 29th March 2013.

log one: i printed this for my geeetech acrylic and lo and behold its not an aluminum frame.

so the frame clips have a 6.4mm opening ans the acrylic is 8mm thick. i try a heat gun first!

log two: i dunked em in boiling water for a minute. slid them in place and set with a clamp until cool. fits!

log three: ok, so i set it up right but there is too much stress with the modified(hot water bath) clips.
i will have to rework the clips to work on 8mm and also i would like it to be a bit wider too.

I just made one of these and it's working out great

I started to do something similar to this with bearings. i found that my wilson extruder body appears to have less than 1mm clearance from the frame. It would loose me about 90mm from the top of the z axis under the mounts.

What dual extruder is that?

It's an Einstein, right?

Yes, it's the old style Einstein dual extruder.
