I needed a pencil extender I didn't really care about breaking/losing when working or travelling. I wanted one I could 3d print for cheap and customise with different colors. When I looked at the other designs - I didn't like how they looked and they all didn't have a cap for travel and tip safety. Without the cap the tips break easily in a pencil case or pocket (even worse it could stab your leg) :(
Also the whole thing is not filled in on both sides in order to be able to use both small pencils from 1cm-ish all the way to full length ones. And when you no longer have the full length pencil and it fits inside the extender you can print the blackwing eraser bottom cap and continue to have an eraser on the other end (a lot of other extender lack this feature). Features also a hole through the side of the main base to see how much of the pencil is left (when you are not using a transparent filament).
So I designed this one with the thought in mind to make it very light and cheap to make on any printer. It took me 2 weeks to get to something I like and that grips the pencil well enough and the tolerances are good. This also took many many many test prints.
Total Weight: 13g
Print Time: 1h 56m
My design was partly inspired by the Mimiku by wada-denki, and the UPH-8000 by Mitsubishi. You can see them side by side in one of the images.
If anyone needs I can customise the length/height of the cap to fit even longer sharpened tips. DM me.
Disclaimer: Since I designed the teeth to be larger than normal for good grip on the pencils by the holder/extender it does chew up the part where it grips with visible lines. I did this specifically to be able to sharpen the pencil while the pencil is still in the extender, because typically you would need to take it out when sharpening - the others ones have a light grip and they just spin in place when you try to sharpen them. Just make sure you have more than you think you need extended so it actually reaches the blades!
