This is a remix of the Wio Tracker L1 E-Ink enclosure with a few changes focused on screen protection and personal customization.
The original case design fit together really well, but the 2.13" ePaper display felt a little too exposed for a handheld/pocketable Meshtastic node. I added a small raised bezel around the display opening and used the existing internal recess to fit a 0.44mm clear plastic screen protector insert behind the front opening.
The clear insert is held from the inside with Kapton/polyimide tape around the perimeter only. It does not press directly against the ePaper screen. It simply acts as a replaceable dust and scratch shield.
For the clear insert, I used a piece of thin rigid plastic packaging from a table saw blade package. Mine measured about 0.44mm thick. Any similar thin, clear, reasonably rigid plastic sheet should work as long as it sits flat in the recess and does not contact the ePaper panel.
I only add the remix for the front. That's the main functional change. A simple: a 0.75mm raised outer bezel with a 1mm wall width, created from an offset curve around the display opening. I've removed my personalized text.
Main changes:
Added raised front bezel around the ePaper display opening
Added ZRD 13 face text
Used the internal recess for a 0.44mm clear screen protector insert
Added back-side custom text
Printed with a dark grey front shell and blue back/buttons
Built around a 3000mAh LiPo battery
Screen protector insert:
For the screen protector insert, I used a 0.44mm thick piece of clear rigid packaging plastic. Mine came from the flat plastic packaging used for a table saw blade, but any similar thin, clear, reasonably rigid plastic sheet should work.
Thickness: 0.44mm
Cut size used: 58mm × 27.5mm
Held in place with Kapton/polyimide tape tabs from the inside
Important note: Do not let the clear insert press directly against the ePaper display. Leave a slight air gap and test-fit before final assembly.
I can add files later if anyone wants them but honestly the only real change was raising an outer bezel by 0.75mm at 1mm wide using an offset curve of the opening.
