Thing is, this coworker has a thing for putting LEDs in his projects, as can be evidenced by the other things I've printed for him, which include a menorah for 5mm LEDs and a miniature version of the leg lamp from A Christmas Story so of course with the Commodore monitor, he started talking about hollowing out the model and putting in a 10mm LED so he could backlight the printout of the Commodore boot screen. Hollowing out the model wouldn't be that tough, but I couldn't help but think - wouldn't it be better to modify the model to support the 10mm LED?
I started with the beautiful original monitor model from the source, loaded the STLs up in Sketchup, (I've included the SketchUp file) and started working on it. My goal was to make it printable with an absolute minimum of supports, and I've accomplished this. The only part that requires supports is the front, and that'll only be around the edges. The back can be printed with supports, but that flat spot is thin enough that any printer that can bridge reasonably well should be able to handle it without a problem. I also expanded the bezel trim for the front so that it is a light press fit - the original design had quite a bit of space around the edges so had to be glued into place. There's a small hole in the rear to route out the wires for the LED.
Note: I've found that SketchUp is pretty weak at dealing with small details on the sub millimeter scale, so I've taken to modeling things in SketchUp using meters. I find it far less quirky, and when I export the STL, most software assumes I was using mm and it should load into your slicer no problem.
Note: I wanted to try Cults3D as a possible alternative to Thingiverse, but after giving it a bit of a look, I'm not super impressed. Feel free to visit my Thingiverse page if they can manage to keep that site running:
I went to school as a mechanical engineer, and got interested in 3D modeling, specifically the SDRC I-DEAS CAD/CAM software system. This interest got me my first job working for a CAD/CAM reseller doing pre and post-sales support. I was lucky to be involved in 3D printing in the early 90s - for a demo of rapid prototyping, I modeled the mouse from my HP-UX CAD workstation and it was rendered via stereolithography. I still have that model, but across the years I stopped using CAD and moved to systems administration. Now that 3D printing is affordable and mostly reliable, I've gotten into it and am having a blast. I printed all the usual cute little trinkets and tchotchkes, but quickly got bored of that. What I find most interesting is needing something, then spending a little bit of time in a CAD program and soon after that having a real, functional version of the part in my hand.
I'm a cyclist and bike mechanic as a hobby and a side job, and have found endless applications of 3D printing to both bikes and bike maintenance. Coworkers have also come to me with many varied requests, each of which has been an interesting challenge and an opportunity to learn.
I am constantly learning, constantly trying to challenge myself to learn new things and technologies, so hopefully as I progress my designs will continue to improve.
