DC Load Battery Tester case

I created this enclosure to work with the 35875TE Electronic Load Battery TesterI purchased from Marlin P. Jones (mpja.com). That module uses a fairly common79mmm x 43mm snap-in form factor so this case should work with quite a few othermodules that share that form factor.I've listed a few below that I think would be likely to fit into this enclosure(some modifications may be required to accomodate the specific features of eachmodule).AI wanted the module to have the option to run from battery power so I've includeda LiPo battery and the Adafruit Powerboost 1000 step-up regulator/battery charger.Also I wanted to keep the depth of the enclosure somewhat shallow and have the USBcharging port on the front, so I've used an Adafruit 1833 USB Micro-B Breakout Board for power so I can rotate the PowerBoost board.The enclosure front and back halves stay together using a snap-fit joint thatI modelled from the screw-less RPi 3B+ case by Malolo. Thanks Malolo! This joint has worked well for me when printed in PETG, but was too brittle when I tried PLA.The Dual LED can be wired to whatever you'd like but I connected it to the twocharging signals on the PowerBoost (removed the LEDs on that board).Sorry my rendering of the 35875TE is not complete - I only modeled the partsI needed to get the enclosure done.I've only tried the enclosure with the 35875TE module but I'm guessing it wouldhave a good chance to work with these below (again some modifications may be needed):(79mmm x 43mm and a cutout of 75mm X 39mm)MPJA 35800 TE: Variable Frequency/Width Pulse GeneratorMPJA 35875 TE: DC Constant Current Electronic Load Battery TesterMPJA 35478 TE: Variable Frequency/Width Pulse GeneratorMPJA 36146 PS: DC-DC Adjustable DC Power Supply ModuleMPJA 36387 PS: 35W Buck-Boost DC/DC Converter with Current LimitMPJA 38425 TE: High-Precision Millivolt Signal Source -10.00 to 100mVMPJA 36139-ME: DC Multifunction LCD Panel MeterXY-FZ35 : Constant Current Electronic Load Tester 5A 35WDROK PWM Frequency Generator module XY-PWM1UCTRONICS Variable Bench Power Supply DSP5005UCTRONICS DC Variable Power Supply 5-30V to 0.6-30V XY-SK35
