Pi Camera Arm for Prusa i3 MK3 and maybe other printers
thingiverse
This arm was designed in Tinkercad.com and printed in PETG, but it could be printed in other materials (no flexi, or maybe yes...). You will need this to complete: 1x pi camera 3x M3x8mm for the links 3x M3 nuts for the links 4x M2x8mm for the camera mount If you tighten more the link screws, you will have a more rigid arm. Not all links would need the same tightness. I think the base can be improved to add some "suspension" and reduce the vibration to the camera. I would work on it and upload it later. For the screws and nuts, I highly recommend to buy this kit (or something similar). It is very useful. You will have enough screws and nut for many projects. https://www.aliexpress.com/item/480pcs-New-Hex-Socket-Screws-M2-M3-M4-Stainless-Steel-Head-Cap-Screw-Nut-Set-With/32816555979.html?spm=a2g0s.9042311.0.0.27424c4dlMLZPX Upgrade Jun 4, 2019. 1.- I designed a new long arm. The original arm was 78mm long. This new one is 105mm long. I'm using one long and one short, but it will depend on your requirements. File "Arm long.stl" 2.- I designed a new base. I had been having some problems with the Octolapse pictures because before it takes each picture, the extrude moves away. This movement causes some vibrations on the camera. So I did another design for the base including an o-ring "suspension". So far, it is working fine and the vibrations of the camera have been reduced. File "Arm Base v2.stl" To assemble this new base, you will need: 6x o-rings with inner diameter 4.4mm and section thickness of 2mm (outer diameter of 8.5mm approx) 2x M3x20mm screw I bought this o-ring kit and used the R-02, but I'm sure you can use something similar. https://www.aliexpress.com/item/419pcs-Rubber-O-Ring-Kit-Seal-Gasket-Universal-Rubber-O-ring-Assortment-Set-R01-R32/32869604493.html?spm=a219c.10010108.1000001.12.f6a8126eet0TU9 You will have to put one o-ring on each printed "washer" and one on each base hole. Total of 3 o-rings for each hole/side/screw. Take a look at the pictures.
