OFFICIAL RELEASE: https://makerworld.com/@VIVI_66/collections/1454030 

• As the caption idicates this model at this point, is only a prototype and is continuisly beeing improved.
• Name Origin: My “Brand name” is VIVI wich stands for VI VIBE (we vibe).
• The wallet series is called VI-Wallet because it can contain 6(VI) cards in it´s standart form.

Prototype log

Prot1, Print1:

Print data: 1h40min and 36g of filament at Normal speed.

Looks: Random-seam looks wierd, low amount of stringing, Lower part of the wallet has slightly visible lines.

Mechanism: The card stopper at the top seems fine. The card ejection system can´t be tested because the lower half of the slider is fused to the sides of the cut out.

Correction: I was able to forcefully detach the slider from the cutout, and have noticed 4 things:

1. The mechanism is way to loud and sounds cheap. (will fix by changeing layerheight from 0.2mm to 0.12mm).
2. The card in the back sometimes doesn´t eject, the reason beeing that the card gets stuck between the shuffle slider and the backwall of the wallet. (will fix by lowering tolerance between the wall and the shuffle slider).
3. The slider has alot of room to move and seems instable. (should improve when I lower the tolerances between the shuffle slider and the backwall as planned in point 2.).
4. The right card stopper broke of when i put the cards into the wallet. (will fix by giving the stoppers more room to move; making them flexible in some way).

Thoughts/Ideas: I should add a cut out on the top to make it possible to pull out cards by hand, also rounding the top corners up could make it look a bit better.

Improvements:

1. Made a new safety system to secure the cards in place. Note: Inspired (But not remixed!) by Hugos Cascade wallet V2.
2. Made a cutout at the top in oder to make pulling out cards by hand easier.
3. Changed the tolerances between moving parts and the shell/housing.
4. Printprofile changes:

• Random seams → Fixed seams.
• Adaptive layerheight smooth → very smooth.

Print data: 1h43min 35g of filament.

Looks: Changing from random seams to fixed and using a better profile overall increased the visual quality by alot, BUT there still is → A decent amount of stringing at the top; will fix by rotating the wallet in Bambustudio. Horizontal lines are visible at the bottom; will fix by tweaking the adaptiv layerheight and smoothness of the transitions.

Mechanism:

1. Huge improvements made on the sounds part, but the ejection mechanism does still make a scratchy noise; will fix by making the slider a bit thicker and decreasing the layerheight a bit.
2. The mechanism was stuck to the casing a little but it was luckily pretty easy to detach; will fix by increasing tolerances back a bit after lowering them by a big amount.
3. It´s pretty hard to slide the mechanism open due to low grip on the slider; will fix by adding some depth in the middle and adding some textured grip there also.
4. The new safety system works pretty well, problem no is that the cards have to much room at the top wich makes them wiggle around; will fix by decreasing the total height of the wallet by cutting 1-3mm in the middle off.

Thoughts/Ideas:

To decrease the sound of the mechanisms movement i could try to add some kind of rails for less surface on surface area → less friction.

The new open part gives the model a slight techy look, and is practical to get a better grip of the lowest cards and to take out all cards at once.

Improvements:

1. Detaching the mechanism from the body was way easier.
2. Added a new grip wich works very well.
3. Ejecting the cards got easier over all.
4. Made huge progress with the safety system, by cutting the size of the wallet about 3mm short.

Print data: 1h 46min 37g filament.

Looks:

Put the seam location to the front of the model, looks really bad. Will change by putting the seam in the back.

Some stringing but not to bad.

The slider does have a special look due to the new grip i added.

Will maybe fix by changing the pattern.

Mechanism:

Nothing worth mentioning.
