On occasion I will do something practical:
It’s not that we needed a rack for those cans, but it did get a laugh from Mary and that’s what counts.
The magic URL encoding all the parameters to generate a rack, using a recent addition to the wonderful boxes.py collection:
https://www.festi.info/boxes.py/CanStorage?FingerJoint_angle=90.0&FingerJoint_style=rectangular&FingerJoint_surroundingspaces=0.0&FingerJoint_edge_width=1.0&FingerJoint_extra_length=0.0&FingerJoint_finger=2.0&FingerJoint_play=0.0&FingerJoint_space=2.0&FingerJoint_width=1.0&Stackable_angle=60&Stackable_height=2.0&Stackable_holedistance=1.0&Stackable_width=4.0&fillHoles_bar_length=50&fillHoles_fill_pattern=no+fill&fillHoles_hole_max_radius=15&fillHoles_hole_min_radius=5&fillHoles_hole_style=hexagon&fillHoles_max_random=1000&fillHoles_space_between_holes=10.0&fillHoles_space_to_border=15.0&top_edge=%C5%A0&bottom_edge=%C5%A1&canDiameter=80&canHight=115&canNum=6&chuteAngle=5.0&thickness=3.2&format=svg&tabs=0&debug=0&labels=0&labels=1&reference=0&inner_corners=loop&burn=0.04&render=0
In order from left to right, the three successive racks represent:
- A good laugh
- Finding that a burn correction parameter of 0.04 produces a much better fit than 0.05.
- Discovering that I must orient finger joints along the same axis to minimize small axis scale errors errors
The Burn Correction Factor encapsulates many physical effects and, much like 3D printing’s Extrusion Multiplier, must be determined empirically.
The axis scale error, however, took me by surprise.The X axis travels on the order of 0.2 mm more along 250 mm, about 0.08%, than the Y axis, even after my tedious calibration. I must do that calibration again, because, as Miss Clavel observed in a different context, Something Is Not Right.
And, yes, that tiny difference is enough to misalign the last few fingers with their holes, to the extent of requiring somewhat more than Gentle Persuasion with a plastic mallet.

I assume the rack is the fancy kind that helps with stock rotation by having the top row drop down at the back.
I wouldn’t have it any other way! There’s now a hand
writtenscrawled tag saying “Use First!” on the leftmost rack.Turns out the cans are slightly conical and require alternate direction stacking for ahem successful operation. Details, details …
Alternate stacking? But that can’t be. Now there need to be two parameters for outer diameter, so the script can create a ledge on one side for the cans to ride on.
This, or the only alternative: Spiral staircase. https://www.museivenezia.it/scala-contarini-del-bovolo/
Ah! A giant vibratory bowl feeder, with cans sorting themselves upright on the way out!
Ed’s gonna have salmon croquettes for miles.
Those are so not happening again. [grin]
I had completely forgotten about the canned salmon casseroles topped with tomato puree my mom used to make when I was a kid. Thanks for ruining my weekend ;)
IMO canned salmon is the most revolting stuff in the kitchen. Mary puts it on her garden-salad-ish lunch, but we have reached an agreement about putting it in anything else.
Julie makes fish cakes with canned salmon. She normally used bread crumbs (gluten free because allergies), but we dehydrated some of this year’s zucchini crop. The zucchini improves the taste, for various values of taste.
Once a month, we get out the Foreman grill and a couple pieces of salmon from the restaurant supply stash. Makes up for the fish cakes.
And yeah, the brand of salmon we use is different, but also the conical can. I’m sure there’s a reason, but I’n not sure I want to know. [grin]
All I know is: those bears over your way must have terrible halitosis …
Volunteers to test that assertion are unavailable. Curious, that. [grin]
