A variant of the back cover (“No.3”) based on the idea that extra external protective cover can be a bit much and what could be the minimalist way to protect the phone.
The bump corners are directly part of the back cover and wrap around the corners, connecting the back cover more securely to the phone. Because of this, I also added holes to corners for lanyards, so it’s possible to carry phone around your neck or side (some seem to prefer that with their phones). Corners add about 1-2mm to sides and top (screen will not touch desk surface if placed that way), so it doesn’t make L5 feel or seem bulkier. Added side benefit is that the corners give some nice extra grip if phone feels too slippery,
Also, the design features a pingu image, both as a hole and a separate file to fill that, so it can be done in two-tone (dual extrusion: the additional file has the white parts - if using single extrusion [still needs other file too placed on the hole] or same color on both extruders, the image is still drawn with print lines - very subtle, see images).
(I used white because had to - no black available today, so no two-tone, as both extruders used white - but it shows the details a bit better, I think. Print made with hobbyist Ultimaker 3S, hard PLA, normal settings from Cura, about 3.5h. GNU GPLv3+. Maybe a SW/StormTrooper version could be made that looked good…)
Maybe we can start collecting these files in a “Community designs” folder…? These stls can be found from: Add new directory for community designed 3D-printable files (!6) · Merge requests · Librem5 / 3D_designs · GitLab
