The NEW Stanley Cup craze! Engineer who created a special tumbler handle to hold his girlfriend's LIP BALM sends the internet into a frenzy - as thousands beg him to sell the design

An engineer who created a custom Stanley Cup handle for his girlfriend to hold her lip balm has now been inundated with thousands of requests to sell them.

Carmela, who has not disclosed her last name, took to TikTok to document the invention journey.

She initially shared a clip of boyfriend Jordan sitting at his desk as he took measurements and sketched out the design.

Carmela joked that 'engineer boyfriends come in handy' before being inundated with requests from other owners of the iconic tumblers.

An engineer who created a custom Stanley Cup handle for his girlfriend to hold her lip balm has now been inundated with thousands of requests to sell them 

Carmela, who has not disclosed her last name, took to TikTok to document the invention journey 

In the clip, which has been viewed more than 14.8 million times, Carmela filmed the process before adding overlaid text that read: 'Your engineer boyfriend designs a ChapStick holder for your emotional support tumblr.'

It was soon flooded with likes and comments from admirers of the 3D-printed product - which is compatible with both Stanley and Simple Modern tumblers.

Following the frenzy around the removable design, Carmela posted a follow-up clip to dish on the motivation behind it.

'I was just tired of my ChapStick always falling off my desk into the garbage can or losing it at work really easily. 

'I bought so many ChapSticks because I lose them so easily and my boyfriend was like, "I can just design that for you."

'So he designed it for me and we did different tests - like a lot of different tests.

'My boyfriend is a true engineer so we did a bunch of different tests, different angles, different supports - you name it.'

The content creator then held the finished article up to the camera as she explained how the handle attaches, adding: 'It unscrews and it's very sturdy.'

The first video featured her boyfriend Jordan (pictured) sitting at his desk sketching up the product design and taking measurement

She continued: 'Another question I have been asked is can you wash these handles - yes you can. 

'They are waterproof. Just don't put them in the dishwasher and water bottles should not be in the dishwasher anyways.'

Carmela has since shared with People: 'It has been an ongoing joke that my ChapStick always rolls off my bedside table and into the trash. 

'Also, I would always lose my ChapStick at work because my scrub pockets are small.

'When Jordan noticed that the handle could come off, he started thinking about making a handle that could hold a Chapstick. 

'He got right into engineer design mode and that's how my video came about.'

She explained: 'We have noticed quite a few people are confused with how it works. I was also surprised that the handle can screw off. 

'This handle we designed replaces your current tumbler handle. You slide your ChapStick in from the top, and then it slides right out. 

'It only falls out if your tumbler is upside down, but then your water will also spill.' 

Her original video was flooded with comments as viewers gushed over Carmela's boyfriend's dedication
