Record Player (Red Solo Cup Edition)

thingiverse

This is a remix for the #RemixChallenge of the Hand Cranked Vinyl Player by Oana. I had stumbled across this by myself previously and after I saw it was on the Remix Challenge I just knew I had to drop what other things I was printing and get to work on improving it! I enjoy printing mechanical clocks, so I wanted to take a look at all aspects of it and set about making design changes for both the construction and more importantly the functioning of it. On the design front I knew I wanted to simplify and attach the tonearm to the record player, both to save plastic and to improve portability. To save quite a bit more plastic and printing time I removed the ghosts from the frame (6.5 hours vs 9.2 hours print time!) but I modified it so that it would also print well without supports near the top of the frame. I initially investigated and printed a Rotary Governor instead of a penny weight to regulate the speed, but the shaft didn't spin quickly enough for it to be feasible. I also tried printing the GRAMiphone horn in hopes of using that instead of the rolled card stock, but the volume and tone were not an improvement. To improve the functioning on the record player, I added a slightly raised circle and 2mm hole to the no-ghosts-support so that a short piece of 1.75mm filament could be added instead of trying to print such a small object. That, and the addition of penny weights for the shaft help it turn more smoothly and the extra weight provides more momentum to help stabilize the speed while playing a record. The red solo turned out to be a good resonator and it was easy to make by simply poking a needle into the bottom and fitting it in the larger tonearm I made. All in all I'm quite satisfied with the remix and I hope you enjoy the red and white printing in honor of the red solo cup and the holidays! UPDATE: Sadly, the inventor of the red solo cup just passed away yesterday. Pour one out for Robert Leo Hulseman! Print Settings Printer: FLSUN Delta Supports: No Resolution: .3 Infill: 20% Notes: I chose a 4mm brim on just about everything to make sure it wouldn't warp or pop off the print bed as I printed with PLA and no heated bed. How I Designed This TinkerCAD I used TinkerCAD to import existing STL files to modify and then export. Assembly Video Assembly Tips and Tricks Add drops of superglue where appropriate. I didn't do it for the assembly video, but it's needed here and there. You may notice a few black dots on some parts. I've used a few (optional) felt dots to make the turntable quieter and to dampen the frame vibration. A Christmas Carol Record Test #RemixChallenge Remix Info
