And (Another) Another Spool-Holder by pgreenland Oct 16, 2012

Description

Needed a spool holder for my printer and iliis's looked awesome. This derivative includes a few tweaks and notes that I used to make printing and assembly easier as well as a parametric spool holder created in OpenSCAD.

Instructions

The spool currently in my holder has a diameter of 16.5cm and a depth of 9.5cm and as such the following measurements have been based around that.

Parts:
M8 Rod (156cm)
M8 Nuts x 26
608 Bearings x 2

1. Print Spool.stl

2. Update variables in Holder.scad, export STL and print or alternatively print Holder.stl which includes a 8mm diameter spindle hole and 33mm spool shaft.

3. Start by assembling the two A-Frames as shown in picture using a 20cm section of rod for the base and 2 x 15cm sections of rod for the diagonals. I found that using four spare rods to hold the frame corners together made it easier to align the holders.

4. Replace the two length-wise temporary supports with 2 x 20cm sections of threaded rod.

5. Replace the two width-wise temporary supports with 2 x 20cm sections of threaded rod.

6. Screw a 16cm section of threaded rod through the left holder, spool and right holder.

7. Place 2 x bearings onto spindle shaft and drop into their slots on the frame.

8. Feed end of filament through holder and alight at 90 degrees to frame to help prevent spool from rolling like mad.
