Hi,
I always wanted an affordable, uncluttered and reliable mechanical pencil that I can always carry with me.
This is the 3d printed solution I came up with. It's a simple mechanism, allowing you to adjust the length of the leads using gravity. I think they are comfotable to hold, but since everyone is different I also made an ergonomic cover for the pen if you don't like the shape but still want to write/draw with it for a longer period of time.
I hope you like it :-)
There are several versions with the following dimensions:
Keychain version: 55 x 12 x 4 mm
Short version: 105 x 12 x 4 mm
Long version: 125 x 12 x 4 mm
Long version with clip: 125 x 12 x 4 mm
Sturdy version (for 2.7 mm leads): 105 x 12 x 6 mm
The hole in the back has a diameter of 4 mm.
How do you print it?
It consists of only one part and can easily be printed in around 1 hour with no supports. I recommend a 0.12 mm layer height, a 20% gyroid infill and PLA. The ergonomic grip cover is optional and can be printed in 45 minutes using the same settings.
How do you use it?
- You need basic leads with a 0.9* mm diameter in order to use this pencil.
- To insert a lead, simply insert it at the hole in the front until it stops moving. Then rotate the pen upwards and press the lever on the side - gravity will do the rest for you as the lead slides down into the pen.
- To store more leads just repeat step 2.
- Press down the lever on the side and you will be able to slide them in. You can store several leads in the pencil.
- In order to be able to write with the pencil you need to tilt the front down towards the paper and press the lever on the side - gravity will make the lead slide downwards. Just adjust it to the length that you desire and stop pressing the lever. This will fix the lead in its position. I recommend sliding the lead back after you used it to keep the PLA flexible for a long time!
*if you need a different diameter just let me know
If it does not work for you please leave a comment or shoot me a message instead of just posting a 1 star review, I'm sure there is no problem that can't be solved.
