Precision Piezo Orion mount for air cooled Chimera/Chimera+

thingiverse

This is designed to enable the Precision Piezo Orion to be utilized with the air-cooled Chimera/Chimera+ and the Cyclops/Cyclops+. The primary difference between the two STLs lies in the bowden tube entry spacing. The Chimera features an 18mm center, whereas the Chimera+ boasts a 20mm center. To utilize the Orion, it must be mounted with a 45-degree turn. This configuration allows the bowden tube to pass through the unused piezo mounts in the Orion. The Chimera is attached to the mount using E3D-supplied M3 bolts, whose heads are countersunk below the top surface level. The entire assembly then mounts onto your X carriage via four M3 bolts (as shown). I have included an example mount that I am developing for my CR-10S. There may be some changes to the design as I continue testing it. Feel free to send any suggestions for improvements. Thanks go out to the guys at Precision Piezo (https://www.precisionpiezo.co.uk) for this fantastic product and their expert advice. Updated 21/07/18 - I have been experiencing issues with the Orion not always triggering, which I attribute to the preload ring in the center not being fully seated. To rectify this issue, I decided to split the block into two halves. The bottom half is secured to the heatsink using button head socket cap bolts (the same ones supplied by E3D). The top half then sits atop the bottom half, and the entire block is mounted as before. The heatsink bolt that sits below the preload ring is now covered, and the preload ring is fully seated. I also added inserts for M3 nuts to prevent reliance on threads cut by the bolts. I have uploaded the Chimera+/Cyclops+ mount, with the standard Chimera/Cyclops mount to follow once it has been printed and tested. This was printed on my S4 with a glass bed, so I oriented the parts to ensure that the mating faces were on the bed surface.
