No pressure. Simply watching this being made was amazing. If you do find a way to mass produce it, make a follow up video. If not, I’d be wondering if there would be any simpler way that a layman could make with semi obtainable intems (in other words a simpler way to make the same general concept). This was all a ton of awesomeness overall, and you earned yourself a sub!

@@markf.9396 it's ultimately down to preference. Some, including me, would enjoy to hear about the whole process, including the difficulties and innovations that might have come within, as such documentation could aid others in either replication or general performance in this field. Others do understandably prefer the pure assembly, presumably due to a relaxing effect it boasts

@alexgac1801 Ай бұрын

Here the whole process : 1) You imagine the stuff 2) You draw it - preferably make a CaD 3D model to test the mobility of the part 3) You plan the machining - I think part of it can be automated nowaday, but it's not too hard anywah 4) You do the machining 5) Assembly - better think about that part during the design, or you will get stumped !

@hiro_444 22 сағат бұрын

Ayo which pen 🤨 /s But yeah totally agree with you, that pen wouldn't be comfortable at all to write with because of how thick it is. I think it needs improvement on the grip part, either by reducing the thickness of it entirely, or by creating small valleys for where the finger can sit on comfortably instead of letting the entire pen be perfectly cylindrical. Personally I like the latter because pen with bumps and valleys like that can use that as it's design and look really good

Забавно, но как раз таки в школе у меня была подобная ручка - на 8 паст разного цвета. Переключение производилось путем опускания кнопки нужного цвета - к ней прикреплялась паста. Чтобы вернуть в исходное состояние, нажималась любая другая кнопка, после чего ручка вставала на "нейтралку". Была из пластмассы правда, и корпус долно не прожил - треснул снизу, а также в районе резьбы крепления одной части ручки к другой - сверху. Для справки, мне больше 30 лет уже) Кстати говоря, писать было жутко неудобно. А вот у одного из учителей я видел версию на три пасты - чёрная, синяя и красная, ручка вполне сопоставима с обычной при этом. Вот это - идеал.
