<p>First of all i'd like to excuse myself if the fit and quality of the files isn't perfect, this is my first design and i bought the printer for the express purpose of making this design for myself.</p><p>The STLs are for the bottom keyboard insert, top insert and a simple screen bezel to protect the display.<br>What i wanted to achieve was an easy to carry and weatherproof solution for digital mode qrp connections so the finished case contains a raspberry pi 3b with DRAWS hat, ATU-100 HF tuner and a 7.8" e-ink display for as low power draw as possible for extended field use.<br>Please see the included parts list if you'd like to make this kit yourself.</p><p>The print in the cover picture is an early prototype so there are some differences between it and the finished product such as 3.5mm audio jack, place to fit the gps-antenna and the 2 DIN connectors for the DRAWS.</p><p>The prints are already cut so they can be printed on a Prusa mk3s+<br>I printed them in colorfabb XT-CF20 so when using PLA please take shrinking in to account.</p><p>-Small tip when it comes to assembly.<br>i suggest using raspberry pi GPIO extenders and a couple of breakout boards, mount one board to the top and one to the bottom of the case you can use those 40 pins for all the USB connections, Mini-din and display and control cables for the tuner.<br>I'm also using ribbon cables connecting the top and bottom halves with a 4 wire ribbon for the power and a 10 ribbon for the keyboard and touchpad.<br>Looks better and is much easier to handle when opening and closing the case.</p><p>And throw in a couple of diodes on the 12V if you're going all in with the draws hat so you don't backfeed anything.</p>
