Like many photographers and videographers, I have multiple devices to put on my tripods. Cameras, phone holder, video camera, and I even have a teleprompter that can go on a tripod. Because of how expensive the branded quick-release plates are for my Manfrotto 701HDV fluid video head, over the years I just kept swapping the one plate for whatever I wanted to put on the tripod. Inevitably, I never had a screwdriver or coin handy to tighten the screws down either. So the screws were always finger tight, which for many things is not good enough.
Manfrotto branded 501PL plates on big photo sites are around $42, and knockoff plates are still between $7-15 per plate on eBay and other sites. Well, no longer!! I found a model for the plate that is 501PL-compatible, bought stainless steel mounting screws, and now I made five 3d printed plates with thumb screws that cost $1.41 per plate.
Now, every device I have that needs to go on my tripod has a dedicated plate to make swapping devices on the tripod head so dramatically easier.
I printed the plates in both Elegoo PLA+ and Sunlu PETG, on a Prusa Mk4. The plates were printed with a .20 layer height (.20 speed profile in PrusaSlicer to be specific) at 40% infill and no supports. You might be able to get away with less infill, but I wanted to be sure they were rigid. Also, the print times and filament use were not that much different. From some quick testing, the PETG prints are a bit more rigid (which I prefer), with nearly the same settings between filaments. Regardless, you cannot go wrong with either filament.
