110 Film Development Reel (Paterson-fit)

There is a newer version of this, with some great improvements. Check out my profile, or click here to go to the new version

UPDATE:
I added tweaks 8, 9, & 10 described below, today (Nov 15, 2020)

I shoot and home-develop a lot of different film formats, and I found myself unsatisfied with the “solutions” I had for developing 110 film, so I started asking around for a printable reel. A friend suggested one from Thingiverse, but also mentioned that they had printed it and it doesn’t work… so I thought I’d start making tweaks to make it work. This is the ongoing result. At this point it probably isn't so much a "remix" anymore, but rather its own entity.

Obviously this is being offered on here so that people can make one for themselves (if you do, please let me know!), but if you would like me to print one for you, I'd be happy to for a reasonable price. Just send me a message and we can hash out the details.

To see actual prints of my design, check out the “Makes” tab (I print basically everything I design.)

Print instructions

Printer: MakerFarm Pegasus 10

Rafts: Doesn't Matter

Supports: Doesn't Matter

Resolution: 0.2mm

Infill: 20% overall with some 100% mesh modifiers in a couple places, for durability

Filament: GST3D / eSun / Any PLA+ (Black & Orange, any color)

Nozzle temp: 205°C

Bed temp: 65°C

Notes:
Brim: I used a 2mm brim just as a precaution against edge curling, but I don’t really think it was necessary. I just tend to default to using brims

Post-Printing
Nothing special for post-printing. Just basic removal of the brim (if used). Also, depending on your printer's tolerances, the center hole may be a perfect fit for the Paterson center core rod, or it may need some minor adjustments. All printers tolerances are slightly different in my experience

Improvements/Tweaks I've Made

1. Wider spine, so film is held better
2. Resized the overall reel width so the film holds properly
3. Opened up the outer-most sprockets/lengths of the reel (they were blocked off before)
4. Reduced overall reel size by removing some of the outer-most rim, also improving liquid flow
5. Removed the brittle locking clips as they were not accurately placed and snapped off easily
6. Resized the male/female center core parts for a better fit (tolerances may vary with your printer)
7. Made a new male/female locking system so that the two parts can be easily separated, which makes it much more easy to remove the film after developing is complete
8. Added inner core ribbing, for an even better fit, which also reduces friction when moving up and down on the center core, making it easier to use
9. Added some tapering to the center core, also for a better fit experience
10. Added some tapering to outer edge for better handling

Remix Comments and thanks
In the end, I made so many tweaks/mods that there are really only minor aspects of the original still present, which would probably classify it more as a borderline “remix”. Still though, giving credit where credit is due. Thanks to the original designer @FabriceL on Thingi for inspiring me to make this one
