These helper blocks should help during the initial BTT Eddy setup guide for SimpleAF firmware.
When setting up a BTT Eddy, one of the instructions calls for placing the nozzle 20mm from the bed. In order to facilitate having to measure with a caliper, you can instead print out one of these springs in order to safely move the nozzle down to 20mm without having to worry about driving the nozzle down on a solid spacer.
When setting up the experimental eddy-ng, the 20mm step is no longer necessary. However, it does require the BTT Eddy to be a certain z-distance from the end of the nozzle. If you are using a mount that has you use the OEM Eddy cover, the spacing between the sensor and nozzle needs to be at least 1.8mm. If you are instead using a mount that leaves the coil exposed, the bottom of the coil needs to be at least 3mm from the nozzle.
I have included designs for both measurements, as well as some non-spring versions in case you just want to hold it up to the nozzle and eyeball it, maybe with a bubble level underneath it.
Print as is with no supports, with 3 walls, and at least 15% infill for the flat guides. Keep in mind that if your printer isn't relatively dialed in the measurements might be a tad off.
