27mm Piezo mount for Re-X Carriage

thingiverse

I would rotate it -90 degrees and print with supports under the "wings" that you use to mount it to the carriage. The way this requires the plastic to flex I think it would be best printed in something like PETG, ABS, or some kind of Nylon. PLA is not recommended. The relevant features are a .5mm slot for the 27mm drilled piezo with a 1.5mm x 5mm slot for the wires and solder points. A tiny .1mm rim was added around the innermost hole to concentrate pressure on the ceramic disc. There is a 2.25mm space for the raised portion of the stepper to fit into. This model has not been tested yet and will be updated if/when it becomes functional. Plans are also underway to modify the top cover to contain the V2 Universal PCB, but that's for later. In the picture, I highlighted the piezo in blue. *update 4/25.* The .stl was updated to give more clearance for the wires and solder points since new leads were added. Electrical tape covered the back of the piezo and shrink rap was applied to the stepper shaft to insulate everything. The shaft fit through the hole without modification, but with the shrink wrap it had to be expanded a little. Firmware is still in development, but tapping the hotend triggers it successfully. A video was made, but it won't be uploaded to YouTube; instead, it will be shared here on Thingiverse. *update 4/26.* It works! *update 4/27.* A mount was added to the top cover to hold the Universal PCB v2.x. It has cutouts for the LEDs and adjustment screws. Wiring can be a bit tight in there, so make sure it's cleaned up to avoid interference issues. Requires 2 M3x8mm bolts with nuts. There can be a clearance problem if the bolts used for the wire harness mount are too long. Either use shorter bolts or back out the one to the right a bit.
