Meshtastic Slim Case - SMA remix

thingiverse

This is an authorized remix of BrianN's *Meshtastic Slim Case* (https://www.thingiverse.com/thing:4828465), posted with permission from the author. The original design is license-restricted and will not allow me to reference as a source. ###What is different: This is *version 2* of a modified case that fits the TTGO T-Beam V1.1 NEO-6M model that has a SMA antenna connector; BrianN's original case was designed to fit the NEO-M8N model that has a u.FL antenna connector. Only the "front" and "frame" models needed to be modified to fit the SMA connector and antenna but I have included all of the required case parts for convenience. I've also added an even "skinnier" version as another option, including a variant that supports antennas with larger SMA connector enclosures. If you have a NEO-6M with SMA connector and want to desolder the 18650 battery holder and use a lithium ion battery, print the slim battery backplate. ###Hardware required: This remix requires the same metric socket cap head screws and nuts noted in BrianN's original design (see diagram pictures for small and large SMA port versions). ###Summary of parts: - *Front* model - Includes *no-logo* and *logo* version with Meshtastic "M" logo - *Frame_oblong-USB* model - For oblong/oval tip magnetic USB cables AND standard USB cables; *also now prints support-free* - *Frame_round-USB* model - For round tip magnetic USB cables AND standard USB cables; *also now prints support-free* - *Back_battery-18650* model - For use with stock 18650 battery and holder - *Back_battery-slim* model - For use with slim lithium polymer battery; *requires desoldering the 18650 battery holder* - *Button_labels_1* - Replaced recessed button labels with separate label plate for multi-color printing; long and short (abbreviated) versions of "Power / User / Reset" text - *Button_labels_2* - Replaced recessed button labels with separate label plate for multi-color printing; long and short (abbreviated) versions of "Power / Prog / Reset" text - *Button_labels_blank* - Blank version for using your own fonts - *Button_tall* and *Button_short* - Print two tall buttons for Power and User/Prog and print one short button for Reset to prevent accidental press (or three tall buttons if you choose) - *Nameplate_blank* - For radio ID; *see example pictures* - *OLED_Screen_window* - Resized to completely hide OLED screen connections; *insert between screen and frame* - *OLED_Screen_shim* - Helps stabilize the 0.96" OLED screen when soldering - *GPS_shim* - Allows use of 12x12mm or 15x15mm GPS antennas; *frame is already sized for a 18x18mm antenna* - *Stand_1_18650* - Fits the case when using the 18650 battery backplate; *logo and no-logo versions included* - *Stand_2_18650* - Same as above, but with deeper front cutout to show radio nameplate; logo and no-logo versions included - *Stand_battery-slim* - From the author's original design for use with slim battery backplate (not 18650 battery) ###NEW UPDATED Slim Case SMA "Skinny" v3 and "Large SMA" variant (1 Jan 2022): ###This remains a work in progress... -Added "Large_SMA_port" models for antennas with larger SMA connector parts -Increased diameter of button holes to 3.51mm in all "Frame" models -Added a diagram to show what size screws to use, and where to use them - 20% narrower version that eliminates nearly all empty space around the T-beam PCB - v3 updates of *Front*, *Frame*, *Back-battery-18650*, *Nut_plate*, *Nameplate_blank*, and *Stand* models - Alternate *Front* model option has button labels etched, no need to print *Buttons_labels* model (updated to correct reversed PWR/RST labels...sorry!) - Uses the same *Button_tall* and *Button_short* models for switches - Added gaskets for top/bottom of frame, and OLED screen window; print using TPU
