Daylight readable Display Case 7" with fine click-dial dimming

Folks, what's with the paltry numbers: 100 downloads and a whopping two likes?! I'm going to yank the main attraction for that. No, just kidding around. But seriously, this is subpar design. If you're not pleased, then don't display it, and if you choose not to display it, don't bother downloading it either. Thanks. When scouring through billions of tiny displays for one that can be read in bright daylight, very few candidates come up. Especially if you're unwilling to break the bank. I managed to find only two in the 7-inch range: -A 1280x800 display with massive heat dissipation, 660 ccd (which falls short when discussing sunlight readability) and a mere four steps of dimming (making it nearly impossible to use as a navigation screen at night while sailing). -NHD-7.0-HDMI-N-RSXN-CTU, boasting 880 ccd, touchscreen functionality, 800x480 resolution, and dimming via PWM (no on-screen display in sight). You can snag one here: https://www.digikey.com/product-detail/en/newhaven-display-intl/NHD-7.0-HDMI-N-RSXN-CTU/NHD-7.0-HDMI-N-RSXN-CTU-ND/7707819 This casing is specifically designed for the NHD display. For dimming, I employed an Arduino Nano (the attached ini-file) and a Rotary Encoder Arduino KY-040 (which I trimmed down using some Dremel wizardry). The display demands 5-7V, which is unconventional in boats or cars. I utilized a DC-DC step-down module (44mm x 23 mm), possibly this one: https://www.banggood.com/LM2596-DC-DC-Verstellbar-Step-Down-Schaltregler-Power-Supply-Module-p-88252.html?rmmds=search&cur_warehouse=CN For the four primary mounting screws, I opted for screwed bushings with a 5mm outer diameter to accommodate M4 screws measuring 14mm in length. I also provided a backplate for standard M4 nuts (_nn.stl). All you'll need is a DC jack plug (glued into its socket using hot glue). I printed the PLA transparent gray, which looks quite satisfactory. The tiny middle ring of the knob3.stl was printed with TPU. Dimming: it dims swiftly when turned, and in fine increments when pressed while turning. The tiny knob tube required scaling to 107% to fit snugly into place. Everything else was printed at 100%. The Shade attachment is crafted from TPU and features a flat design, necessitating a spacious build area. Its largest dimension measures around 400mm.
