Description
Update 12/12/2025: I adjusted the bottom part (the pins are slightly narrower and there are four of them).
I made the top part a millimeter deeper overall, so that the display should be better protected.
Update 09/14/2025: I adjusted the files so that they fit more snugly and the display no longer has any clearance.
This is a remix of the Upgraded Triangular Prism 3D Enclosure for Trmnl 7.5" .
I made several changes to improve printability and usability:
Two-part front panel → Allows easy two-color printing and provides a more convenient way to route the e-paper cable.
Two base versions → One base with a hole for an SMA connector (for using an external antenna, useful if you have reception issues), and one without the hole.
Improved locking mechanism → Adjusted the snap-fit of the base to reduce overhangs and make printing easier and cleaner.
This remix keeps the original triangular prism design but makes it more practical to print and assemble, especially if you want a two-tone front or need an external antenna option.
