MCD Roller shades with oval bottom

[George]

I hope @ChrisBair doesn't mind that I point y'all to his post on FB for his shade pull design. You'll need access to 3D printer to get some. I contacted a local business for an RFQ in black ABS and ASA. I know very little about 3D printing but I see that ASA is better in UV light 🌞
I'll update here when they respond with a quote.
Look down through this FB for his post for his name.

We will be home from our 4 month trip on Saturday and will try this on my 3D printer

BTW - Good job @ChrisBair 👍🏼

3D printing source:
The local public library where my brother-in-law lives has a 3D printer. Very reasonable cost he says.
So if you want some of these you might check your own local library.
My RFQ to a local business is yet unanswered.

My son ran a print using ABS filament today. Just an FYI, the file prints one of each pull tab with each print job. They turned out great - thanks to @ChrisBair. Here’s a pair of pictures.

Looks great. I was hoping there'd be a way in the slicing app to delete the logo one. I have access to 3D modeling. software. Maybe I can get it done there.
Do they fit very tight? Like probably won't move in an 6 hour earthquake?
I'm learning about FDM 3D printing and have in my shopping cart a Flashforge Creator 5 Pro.
I did learn that ABS is a filament that puts out toxic fumes. Hope you're ventilated.
If your son has a recc. I'd be glad to hear it. @Oregon_Camper too. (hope you got home safe & sound)

I've deleted the logo pull tab but cannot upload a .stl file here.
Download the attached file and change the extension from .zip to .stl

Won’t be back to the 5er until tomorrow for fitment test. He bedded the tabs after the first print went sideways. The next two prints did well.

I kind of like the logo tab as our last name starts with A. 😀 And the logo tab seems more substantial/durable. I’m thinking a filled tab might be the best for durability.

Works well. I had red filament in my printer and asked my wife how she like it. She said...well, print it again in black so it matches the shades and lets see.....so, here it is in black. I like it. For the ~.03c to print one, I think I'll be doing all of them.

With no disrespect for @ChrisBair’s design, I find the geometry makes it hard to pull the shade down behind my couch/love seat/dining table. It is also not workable on any of the bedroom shades, at least how we draw them. And a tighter fitment would help keep the pulls in place.

A wider, tighter attachment with a wider pull-tab projecting into the room (90 degrees to the curtain) might help in all of the mentioned locations.
