Adjustable Pencil Extender / Holder for Short Pencils (Upgraded)

(Note: The original file names are in Turkish. "Kalem tutucu" translates to "Pencil Extender/Holder" and "vida" translates to "screw".)

Don't throw away your short pencils! This functional, mechanical pencil extender features a threaded collet mechanism to securely grip your stubby pencils, allowing you to comfortably use them down to the very end.

⚡ Quick & Reliable Print:
This is a very fast print, taking approximately only 27 minutes! It's a perfect, practical tool for artists, students, or anyone who hates wasting pencils.

💡 Design Update (Stronger Build): After field-testing the initial prototype, I noticed that the angled/slanted gripping jaws could break under clamping pressure. I have completely redesigned this final version with straight, thickened walls. It is now incredibly sturdy, won't snap when tightened, and holds your pencils perfectly securely!

Multiple Tolerances Included:
Since every 3D printer has a different level of accuracy and calibration, I have provided the screw part ("vida") in three different tolerance clearances:

0.1 mm: For highly calibrated, precise printers (Tight fit).
0.15 mm: The standard medium fit.
0.2 mm: For older or less calibrated printers (Loose fit).

Print the main body ("Kalem tutucu") and choose the screw tolerance that works best for your machine!

File Formats:
I have included STL, 3MF, and STEP files so you can print it immediately or easily remix and adjust the dimensions.
