HP - Heltec Wireless Paper Case for Meshtastic

***Redesign 03/01/2026***

• Button base was rounded to avoid warping of corners.

• Fillet was added to the cover's side posts to re-enforce weak spots.

• Middle frame was redesigned to apply even pressure despite battery size which was important to get the triggers to work. Now a battery is no longer needed for the mechanism to work.

• Triggers were redesigned to make the buttons to have even contact, no more crooked buttons

Materials:

• Heltec Wireless Paper

• 3000mAh Battery

• PLA

Goals:

• I wanted something simple and clean, no screws or supports needed.

• A nice flat 3000mAh battery that gives a decent runtime

• Needs to be compact and easy to slip into my pocket comfortably.

• Be able to press the buttons from the front unlike ones already out there.

Printing Instructions: 

• All files have the parts in the best possible printing position, so just add them to your plate and print.

• No supports needed, other than the spot where the belt hoop is, so block the supports for just that spot. 

• Print the triggers as slow as possible on their own to prevent any imperfections, this is the most important piece to get right.

• I print everything with a layer height of 0.16mm line width 0.42mm
