This is an attempt to replace magnets and springs. After continuous iteration and testing, we finally succeeded. It’s a perfect replacement.

I eventually designed a pair of flexible material holders with an inclined angle for insertion, one at the top and one at the bottom, using two 15mm TPU pieces as elastic support. After testing TPU 95A (Fusrock), the feel of pressing with two pieces is the best. Due to the potential differences in rigidity and elasticity among different brands of materials, I have designed six reserved holes. This allows for controlling the pressing feel by, for example, increasing from two to three pieces of material, enabling customization of the desired feel. I hope my alternative design solution can help you quickly utilize the "Ret retractable Ballpoint Pen" provided by @wuguigui.

Regarding printing, it is best to use a 0.2mm nozzle for finer details.

It works! I only have a .4 nozzle so it’s not the prettiest, but it’s functional! printed in PETG and added (2) 15mm pieces of Tinmorry 95a tpu with a few drops of super glue. Very cool design that functions as intended.

Thanks for sharing, the simplest and most user-friendly material currently known is PEBA, this material has excellent toughness, elasticity, and fatigue strength, cutting it into two pieces is best, many other materials will recover after prolonged extrusion but will suffer from fatigue

Replying to @jindouyun :

my wife said stop telling me this. I have so many rolls of filament already. But now I need some PEBA. LOL. I have been using this "spring" for many weeks. I am a server/bartender so I use my pen constantly. The pen broke but your magnet replacement is still working perfectly! I printed a new pen and am still using the same magnet replacement. excellent design. elegantly simple and effective. Thank you.

Indeed, it's usable, and the rebound feel is pretty good

Right it's actually quite good and you can adjust it yourself I've printed many pens and can easily give them away

Replying to @jindouyun :

The magnets arrived today, and after using it I think your design is absolutely brilliant! The tactile feedback is strong and resilient, much more solid than magnetic stickers! And it doesn't require any additional accessories, the concept of 3D printing is perfectly demonstrated. Sir that's brilliant! Love it, love it!

Lovely. Perfect print.

Pay attention to using filament with good elastic recovery, such as PEBA material; regular TPU may suddenly lose its elasticity after prolonged compression

This is an underrated model, I wish more people woud see this! This is really cool!

@jindouyun

After prolonged use, there is a small bug. Due to the issue with the flexible material, it needs to be retracted when not in use. The purpose is to allow the flexible material to return to its original state. Forgetting to retract it for a long time can cause the flexible material to lose its elasticity all at once
