Description

Hey All Me Again!

After a lot of feedback, critiques and trialling, I have built upon the "Original" and the "v2" adapters that I Previously Released!

I Have spent alot of time dialing in the tolerances on this model, such that it fits the helio with a nice click! However, as some will have noticed, a .2mm nozzle is REQUIRED to print this adapter this time round! Unfortunatly it is required to print the walls around the adapter to insure the clasp doesnt buckle.

Print as is, laying flat, not fast, not slow, no supports, no brim

Ko-fi: https://ko-fi.com/x169_

Some improvements:

-> strengthening of the loop lug by adjusting the print direction of the strap.
-> Added the most requested feature... A BETTER Latching system, Which Perfectly meets the original whoop clasps design!
-> Major thickness decrease around the top section of the adapter, down to zero added thickness!

I would really appreciate any feedback. And if you like my work, please consider upvoting and boosting my post on Makerworld! Its Free and helps massively!

Any questions please feel free to ask!
Peace

Just made a few changes into the file, i've moved the holes 2mm up and add a second band loop.

@staryfil

Do you have the 3D model?

@user_1256315420

where is the file for this ??

@user_1480600186

Yes could you please share the 3d model or file?

@VhugoSilva

I would like to propose the following changes: 1- Add one more loop where the WHOOP strap band passes through, so that the fastening method matches the WHOOP design. As it is now, when worn on the wrist, it looks more like the whoop. 2- Move the hole where the metal frame fits by 1–2 mm upwards, allowing the loop to sit better over the Helio. i made the chances using glue and a hot iron, pictures attached

@kylehui

is this whoop 4.0 or 5.0

@VhugoSilva

Replying to @kylehui :

4.0

@ludodo

that is a nice model, it scratched my sensors tho. it would be nice to make use of the little metal adjustment band contraption in your next revision (V4) to make the whole sturdier. if possible to find a way to prevent the scratches on the sensors but it seems complicated without compromising the height

(Edited)

@user_849490245

Great model. Sadly it scratched my sensor. The metal knobs protrude inside. Is there any way to fix it?

@ludodo

same here

@VhugoSilva

Very good adapter!! I had to print twice, because the first one broken while i was trying to insert the Helio. But it's firm on the Wrist.

@Beolink3

Are you using a Whoop 5.0 Band ?

@VhugoSilva

Replying to @Beolink3 :

4.0 whoop aftermarket band

@TehBeh1887

I also printed the adapter with a 0.4 nozzle with thin wall detection and Arachne. Everything worked great so far. The only problem I have so far is that the cap opens too quickly during sporting activities. Maybe you could add some extra "nubs" to the adapter. :) Nevertheless, thank you very much for your great work! I have marked the areas in red that could improve the locking mechanism

@otidotid

bro, why did you make single strap slot? won't the strap loosen during heavy sport use?

The designer has replied

@ste3l

hey! good question, after a lot of testing having two slots introduced a stress point and would likely lead to it breaking easier! where the band wraps under itself the mix of friction between the strap and the lug and the strap itself are more than enough to stop it getting looser

@tomoslono

Second layer prints partially in air above the build plate.

The designer has replied

@ste3l

what nozzle size are you using? if your using .4mm (which I don't suggest) you need to change the first layer wall width to .42 instead of . 5

@tomoslono

Replying to @ste3l :

I'm using a 0.2 mm nozzle. Classic wall generator has the side opposite of the loop lug not print at all on the build plate on the first layer. I had to lower the part 0.1 mm below the build plate so it could create a proper extrusion there. I also tried increasing first layer thickness to 0.12 mm, which didn't help. Arachne makes it kind of work, but on the same side the first layer now prints as a disconnected line that doesn't touch adjacent plastic at the corners at all. At least it works enough to have the part adhere instead of lifting mid-print, but after removing it from the build plate, that same disconnected line was left just partially dangling and promptly peeled off.

@user_2730938085

The other part that connects with the adapter also need to be printed or does it come with the whoop strap and where can I buy whoop strap with it logo even if it is fake

@user_3053146911

Does this mean I can lock the strap without the need of the device (whoop pod) itself aswell?

The designer has replied

@ste3l

all you need is the helio a strap and this adapter!
