Optional tighter and looser fit parts for dimensionally sensitve components of the rewinder.
These allow for variance in printer, slicer, bearing dimension, and fit preference.
Print both the bearing size tool and gear size tool. You should use the same slicer setting you will use to print the rewinder components.
Use the pockets on the bearing sizing tool to characterize the outer diameter of your bearings. Try the bearing out in the "L" (looser fit) pocket first, followed by "N" (nominal fit), and finally "T" (tighter fit). Select the pocket which has the desired trade-off between retention and seating force.
Use the "L" nut and "L" shaft if the "L" pocket gives the best result. The "T" nut and "T" shaft should be used if you prefer the fit of the "T" pocket. If the "N" opening yields the best fit, you should stick with the nut and shaft in the base thing.
Use the posts on the same tool to find the best fit for the bearing's inner diameter. Again, start with "L" and then move to "N" and "T". Select the bearing insert and large gear which correspond to your desired fit. "T" and "L" components will comes from this thing and "N" components from the base rewinder.
Printing components where the inner diameter of one must mate to the outer diameter of the other compounds this dimensional tolerance problem. So, five variants of the small gear are provided including "XL" (extra loose) and "XT" (extra tight).
Use the separate gear size tool to select the best of these five options. Try the openings on the gear tool against the post previously selected on the bearing tool. It is easiest to go across the gear tool from "XL" to "XT".
Select and print the small gear version that provides your desired fit.
- all components except beating insert updated to v1.1
- large and small gears update to v1.2 (added chamfer for easier assembly)
- earlier gear update included a flawed large gear. This problem is fixed and correct parts are posted as v1.2.1.
- cap and gears updated for easier assembly and use
