Description

PDF

This pencil uses a hidden compliant mechanism to hold the lead securely.

The biggest design challenge was getting enough grip to hold the pencil lead in place when writing

Custom Name

You can add your own name easily, 
or maybe your company name like PRUSA
(Fusion360 name plate provided)
Other option is remove it and print it blank.

Made for 2mm pencil lead embedded complaint design

Printing Settings

Design for PETG 0.4mm nozzle, 0.2mm layer and 0% infill, on Prusa Slicer
After printingw/ 2mm Hex key, spin it to clean any stringing left andprinting more than one at time improves quality a lot

to ‘softener’ the mechanism 


Add your Name - optional

On Slicer load the fileDelete the existing NameOn Fusion file Edit Sketch
then export mesh fileselect pencil > add part 
 
 it falls in place nicely  

What to expect

The lead is held in place quite firmly after button released. 
The pencil lead may not slide down by gravity when pressing the button. 
To improve it, first softer the mechanics by pressing harder around the button before loading it.  Expect to have to use both hands in most cases. 
The button is part of the “shell” not a separate object.

Please leave me some feedback so I can improve de model. 

Cheers
