Fidget spinners as an apprentice project
Carrying out your own projects even during an apprenticeship? That’s typical for us. It’s also normal for us to have fun and to apply what has been learned to our own ideas. So, let’s take ideas out for a ‘spin’! Occasionally, our technical apprentices apply also their theoretical knowledge to ’non-GEZE products and show us what they have learned.
Apprentice project fidget spinner
Precision is the name of the game in production
The completed fidget spinner
Our apprentices always manage to impress us with projects that have little to do with our core business. Initially, the bee hotel they built, and the swinging lounger, were the starting point for the company’s biotope; on another occasion they designed and produced an exclusive give-away for school pupils who wanted to discover our training professions: a fidget spinner.
These small toys that can be spun between the thumb and index finger have conquered the world over the last few years. They’re even considered useful: they combat boredom, nervousness, and help when stopping smoking. Indeed, Forbes magazine stated that the spinner was the “must-have office toy for 2017”.
So that it spins quietly and for as long as possible, good materials and precision during production are required. Our apprentices took on this challenge and produced a GEZE spinner.
Plenty of practice and teamwork
The project spans the entire spectrum of product development: getting the idea on paper, designing it in the CAD programme, creating prototypes with the 3D printer, planning production, and also ordering materials of course. They independently selected the tools, set these up, used CNC milling and turning machines, deburred, filed, tested many times over, and gained advice within the team. Enthusiasm was writ large on all sides: our apprentices could demonstrate what they had learned, and the curious pupils were thoroughly impressed with the unusual gift. A few even suggested at the end that the fidget spinners should be added to the GEZE range... albeit in vain, as we continue only to produce door, window and safety technology solutions. And so the fidget spinners remain an exclusive rarity. However, we’re looking forward to the next projects!
This resulted in the fidget spinner
Step by step towards a completed product. The apprentices were supported in this stimulating project by the master trainer and the training manager.
Design of the prototype: Drawn and discussed on paper, developed in the CAD program, and transferred to the 3D printer.
What materials are required for the fidget spinner? Which tools are necessary? Our apprentices solved these issues on their own.
The prototype is printed with the 3D printer and the ball bearing is inserted: the spinner starts turning! The team discusses the next steps for subsequent production.
The material used for the fidget spinner is an aluminium alloy. Drill holes are created on a CNC milling machine. Then, they are deburred manually and the outer contour is milled.
The burrs on the body are removed until the body is smooth and clean. The result is the first cleanly milled initial mould for the fidget spinner.
Plastic rods are inserted into the CNC turning machine and machined to make the handle. A second CNC turning machine creates the gripping surface.
The handles consist of an upper and lower part. Several variants of the concave gripping surface were created and tested to determine the perfect grip shape.
Press in weights
The six brass weights are carefully placed into the initial mould of the fidget spinner so that they also remain in their positions during play.
Initially, the fidget spinner is anodised in blue, and a laser is used to create our logo. The result is well worth seeing: it fits comfortably in your hand and spins astonishingly quickly.
Proud manufacturers! Many thanks to all apprentices, and of course to our master trainers and training managers!
