LED Bottom Lit Display Base

thingiverse

This is a LED backlit (or bottom lit) display stand for your 3D prints (I'm using this one for the glow in the dark Eiffel Tower). But It could be used for anything that'll fit on a 135mm x 135mm platform. The base could be scaled up to match your need. It may throw some of the geometry off for the screw holes and the wire pass through hole. As well as the PCB designed for this stand. For this project, I used a black PLA for the base, and a wood filament for the outer housing. The wood filament was sanded down using 80, and then 220 grit, and then stained with a polyurethane stain from Lowe's. It only needed one coat to get my desired shade. I used a 3mm sheet of plexiglass that was scuffed on one side to create a "frost" effect. I'm not sure if that's going to be the final piece for production. I may use the same plexiglass but pickup some frost film from Lowe's and see if that diffuses the light any better. I've attached my gerber file if you'd like to use the PCB as well for the main lighting. I didn't realized it until after the fact, but my Blue and Green terminals are reversed. So from top to bottom its 12V, G, R, B. Just a FYI. The current PCB supports 64 5050 RGBs. I have a second (way more polished) PCB that I'm waiting on from JLCPBC. That one will have 90 LEDs As it stands now, the base is super bright. Pictures will get updated as this project progresses. **UPDATE 01/31/2021** I've found that with the PCB being in the enclosed box. It does tend to get very warm. Maybe even a little too warm. I've redone the bottom plate to allow for ventilation, as well as cut down on print time. V2 and V3 are being added. Hopefully it'll allow the LEDs to breathe a litte better. I also corrected the wire pass through in the base so it aligns with the V2 PCB inputs. Also, my LED PCB V2 just arrived. With having 90 LEDs on it, it makes this base SUPER Bright. The new design not only adds more LEDs, but also corrects the Blue and Green lines from being mixed up. And it's properly labeled on the silk screen. I'll also be including the gerber files, BOM file, and pick and place files for you to use. I had JLCPCB do the assembly for me this time to cut down on the frustration of soldering 90 5050 LEDs, and 90 0603 resistors. I'll post pictures of the new base after it finishes printing, and with the new PCB mounted in. **UPDATE 02/05/2022** The V2 of the LED board is complete. I ended up swapping out the RGB controller to another version of the Govee. https://www.amazon.com/dp/B07XBSN3Y5?ref=ppx_pop_mob_ap_share&th=1 It gives you way more color options, bluetooth connectivity, and music functionality. I'd consider this project complete. Also, I have a few of the 90 LED boards left over if anyone is interested in purchasing one, either comment or shoot me a message.
