Attempt2 Print

I'm going to save my Yousu Galaxy Blue for end-use prints since it's one of the few fancy colours I still have in stock and I don't really want to buy more filament because I want to eventually switch over to TeamResin with the #SecSavr Suspense [gd0105].

It was all excited when the bottom strap loop actually worked, but I didn't have enough clearances for the top strap so it never clicked in, unfortunately. I've now made sure that there's a 2mm offset clearance from the 1.5mm pinhole (so 2.75mm clearance total). 

Having Fingers 2-4 on the same level is perfectly fine, surprisingly. Finger5 is still what's failing the solution.

My next idea was this. I put my scale against a wall and measured how much force Finger5 could push outwards, and it can do 200g without much effort! Unfortunately, this solution increases the overal length to an eye watering 108mm. The white edge also increased 8 -> 9mm.

Finger5 still fails. On the plus side, the strap succeeds!

So I wore it overnight and here are my thoughts and observations:

• The strap needs to be more centred.
• The design only needs a bit of persuasion to get through the end part of a sleeve. After that, it can slide though the main length without impedement.
• The cuboid design looks fine on my arm. Larger than a watch? Absolutely, but since the sleeve neatly slides under it, it's seems to blend in. (White gloves would take up about the same visual area.)
• That steep angle needs to go.
• It doesn't seem that my skin had trouble breathing. I'll stick to 20mm bands though, since the band is the main thing touching my wrist.
