Update 5/5/18: I am satisfied enough with the design and the fit that I consider this to be finished, which isn't to say I won't keep it updated if there are errors found or someone has a good suggestion.
Update 5/9/18: I have recently designed another style of enclosed spool holder that doesn't use a central spool core - https://www.thingiverse.com/thing:2900930
While inspired by the Spannerhands spool system, I wanted something a little different so I designed my own enclosed spool holder system.
I designed this to be parametric and stackable/interlocking, usable in either a horizontal or vertical orientation, for which I designed the spool core with a lip on one side to assist with horizontal usability. And, there is a spot to stick your desiccant packets.
- Base and Lid - sized for 200 mm x 70 mm spool (customizable in .f3d file)
- Spool Core - sized for 54 mm inside spool diameter (customizable in .f3d file)
- TPU Seal - (size will auto update if customized)
- Spool Retaining Insert - optional, x2; for horizontal use (size will auto update if customized)
- Latch - print-in-place hinged latch or some-assembly-required latch
- PTFE Coupler - m6 or m10 threads (have also included a m10 swivel coupler)
- Bearing Mount - x2
To customize the size of the spool holder, open the .f3d file in Fusion 360, Click on "Modify" and select "Change Parameters". You can easily change the following settings:
- SpoolDiameter (200 mm minimum, or the hinges mess up)
Then just re export the .stl files and print :)
- m10 or m6 PTFE Coupling (your Preference/Availability)
- 2x - 608 bearings
- 4x - m3x12 button head screws if using the Some-Assembly-Required Latch
Default standard/imperial config (cheaper for me) -
Alternate metric config (customizable in .f3d file) -
- 2x - m6x20 Machine Screw
- 2x - m6 Nut
- 10x - m3x8 Screw (or m3x12 + m3 Nut)
4/23/2018 - Initial Upload
4/25/2018 - Changes to hinge setup, switched inside/outside hinges so bottom is on the inside and will support most of the weight if you want to use a wall mount with this. Added PTFE Couplers
4/28/2018 - Decided to remove the interlocking portions on the top and bottom of the spool, they didn't work all that well and required supports for printing the base and lid (I may revisit this and try to come up with a better way). Also removed the fillets around the nodules on the side for stacking (works better in my opinion). Added swivel PTFE M10 coupler for easier use in any orientation (tolerances are pretty tight though).
5/5/2018 - Reworked the Print in Place Latch to give a little looser tolerance for easier break free after printing and less chance of snapping the latch. Added a Some Assembly Required Latch which uses m3 screws instead of the printed plastic pins. Fixed error in Seal dimensions calculation, was being printed 0.4mm too tall/wide. Added small inset to hold nut used for hinge.
5/8/2018 - Corrected some issues in the .f3d with improper constraints in the design causing glitches upon resizing
5/21/2018 - Modified the PTFE Swivel Coupler to be easier to break free
Base, Lid, Spool Core, Bearing Mounts, Retaining Insert, and fixed PTFE Couplers - Dealer's choice; use your preferred layer resolution and nozzle size; should not require any supports.
Swivel PTFE Coupler - .2 resolution; requires a fairly dialed in machine due to the tight tolerances for the print in place swivel portion; should not require any supports.
Seal - should be printed in flexible filament, otherwise what's the point? :)
Print in place Latch - this is printed on it's side and will need supports, I also suggest 3 walls to ensure the pins are mostly solid.
Some Assembly Required Latch - printed in same orientation as Print in Place Latch, needs minor supports. Insure no supports are printed inside threaded holes on inside portion of latch. Break apart when finished for cleanup, then assemble with m3 screws.
