That's what TPU is. Maybe you're referring to something else?
I guess so. In our country Flex filament is not named as TPU. Flex filament has a shore duro of 95-96. Printed with thick walls has enough rigidity to hold a battery but still can be flexed so as the battery can be inserted and the diameter adapted to it.

Hi,
I made a similar holder using ABS purpose of my holder is to keep cells out from each other and help with final assembly. The holder is modular I can stack 2s3p,4s3p, or e.g. 6s3p pack. I use CA glue to fix batteries to the holder. Later I gave up using this because I don’t have my own printer.

Your batteries are welded together, which becomes problematic going through airports. I would call that a battery pack, and not a holder.

I love this TPU for the clips. I beefed it up a bit and it becomes stiffer with each battery installed. Now to add the electrical connectors. The Orange parts are printed from PAL for rigidity. This is the Gator edition of my battery holder.

Side note, I had to manually chamfer the two bases where the connector slips over them for a nice fit. I went back into Onshape.com and chamfered the drawings so they'll just print that way. I also am having to use a good spray of Aquanet on the bed to keep the prints from releasing too early. A bit of alcohol and the bed wipes clean. The 1.75mm you see in the connector are through the bases as well. They are so you can use a bit of filament to hold things together.
