MP Voxel/Flashforge Adventurer 3 Filament Colorizer

thingiverse

This project has sucked up a lot of my life since my first couple of versions I posted. I went through a lot of failure but learned a lot too. This was my first technical 3D design ever and I definitely probably did much of this in a very inefficient way but I also learned a lot about how I could be doing things better in the future. V5 - Working iteration Using bryanduxbury's https://www.thingiverse.com/thing:13624 as a guide to build a 4 sharpie colorizer using the shallow angles mirrored on both sides to get around size limitations and increase color customization and coverage as well as 1 piece arms and the best peg design for stability I could think of. 5_1 placed markers incorrectly causing filament to rub against back left marker 5_2 experimented with fixed in place wheel, reintroduced some tension problems. Fixed wheel idea scrubbed 5_3 marker positioning required too much post process sanding to get full coverage, moved closer together. shortened wheel arms to reduce creaking noise caused by flex. 5_4 fit of markers too loose could become displaced and not colorize filament. added support material 5_5 fixed most of market fit and colors are smooth but arms and full 1KG filament had ~15 degrees of sag from position of base. Very aesthetically ugly and top markers were still somewhat loose. 5_6 Added stabilizing geometry to arms to reduce sag. Sag reduced to <5 degrees. Added upper marker support to keep them in place. So far I have one had one marker come loose once or twice but it only reduced contact not came away entirely but still looking to fix that. A small amount of sanding on the connection points was required for fitup and I also recommend removing any auto supports placed inside the filament hole as it is very difficult to remove and it will depend on how well you can print overhangs if you want to leave supports in the sharpie holes. V4 Iterations on integration of the arms and wheel of 3DBROOKLYN's filament guide https://www.thingiverse.com/thing:4024617 to prevent any more friction failures. Noise issues persisted and color was overall disappointing V3 All iterations were failures due to too much friction causing overtensioned filament I could not resolve in the base design V2_1 V2 base had a break after a few short runs so I rotated the base to match previous, non-breaking, bases and closed and reinforced back hole that may have also played a factor as it was the fail point. V2 Testing completely new design After consideration I ditched the 3 sharpie attachment from taras. Its good but size limitations are pretty firm on this printer. Instead using the 2 sharpie filament colorizer by cyclone https://www.thingiverse.com/thing:11742 I also changed the orientation the spool is meant to be held to eliminate the twisting path that cause the noise in V1. Note that means you will need extra space for the spool's clearance. This is printed in 3 pieces in large part because I wanted it to be printable on the Voxel's small build volume. It is possible to use it with just the interference fit but I would recommend gluing it in the long run on this version. Also I printed with a brim and would recommend a raft or brim for this one as the ring arms have a fairly minimal contact area with the bed and linear supports. V1 *Editing in important note* After running it with some of my more fine tune methods with more aggressive retractions I have found this design loud and will be releasing a 2.0 sometime in the near future aimed at eliminating this flaw. Only print if a clicking noise every retraction is something you can tolerate. This is something I threw together today after my clear filament came in. I used Kickpunder41's redesign of the Adventurer 3 holder that fit so well in my Voxel And also taras' 3 sharpie color blender for an Ender 3 here https://www.myminifactory.com/object/3d-print-138663 I added what should function as a little clip to keep it from slipping. And the reason I designed this was so that I would not lose z space in such a small printer. Drawbacks are that some small amounts of sharpie ink will get inside your tubing and on the drive wheels that feed into the printer but nothing a little rubbing alcohol shouldn't fix if you need it clean again. Also the side panel cannot be on but the holder can still hold a 1KG spool easy and the colorizer is still removable to make changing spools and operating without it both simple.
