3-D Printing Missing/Broken Parts?

[rld-tv01]

I 3D printed a face mask for a 5 inch TT5. I did it in 2 parts; one for the out facing mask and the 2nd for the piece that holds the CRT. I printed fasteners for metal shelf poles which used real metal bolts. I made a custom fastener to hold a 17 inch LCD TV on one of the metal poles which I used as a 2nd monitor for Windows but the fastener broke after a year. Also the fastener broke on one of the ones holding 2 poles together. I used a cheep padlock from the dollar store which replaced it. I 3d Printer a couple TV channel selectors. I 3d printed some bolts and nuts but found they broke easily. I 3d printed a holder for an action cam which also had one piece break. I use PLA filament. Most of the stuff the broke had a thickness under 1/8 of an inch. The TV mask is about 1/4 inch and is pretty strong. I took a local free class about 5 years ago where the instructor built a rocket in class. It was built in stages with each piece fitting together like a vacuum cleaner tube. I printed a box with a lid which fit over the box. I 3d printed a Kraft TV show 1/3 size cameraman. It took several tries to get the camera overhang to not fall off. I printed it in one piece so the wheels didn't turn or the cameraman swivel on the cart. I printed a sprocket for the ships wheel on a Western Visionette mechanical TV. I didn't have the screw threads on the end so it has to be stuck in versus the ability to screw in/out. I purchased a cheap CNC for $200 but paid $300 more for software which allows carving on 4 sides. In my case I have to manually flip the object. I could buy a rotisserie spindle which my software supports but then that would add another layer of cost. I good thing about CNC is that drill bit are sold with many angles 15 degrees to 90+ degrees so the bit does the angles versus your design. ie. inside of a TV mask in the software is a simple like in a circular type curve but the drill bit can make it 45 degrees routed all around the edge.

Wow!!! We will be in touch! I have seen Dave Tipton on his YT channel acquire one for his vintage radio restorations and he has gotten a lot of use out of it. He creates winding spools for rewinding transformers, brackets, radio knobs etc. These plastic yoke covers have been a pain in many restorations. I've used super glue, epoxy, Gorilla Tape et. al. in an effort to keep the original functional but right now, I have an Admiral and an RCA on the shelf because there's nothing left to mount the centering magnets on.
