Tay cầm tập resistance band

I needed some handles for my resistance bands exercises, but they are stupidly expensive in stores, and I was not happy with the other models you can find here
So here's mine

I designed it with chamfers rather than fillets ‘cause it’s still better with fdm printers

I printed it vertically, with 100% infill and only 1 wall (and an old pla)
And surprisingly it works
(I thought it would quickly snap in this orientation)

EDIT:
I slightly improved this, making it a bit thinner and with bigger rims
I also added a bigger one, for bigger bands, but it doesn't fit small hands

I left the old version as v1
