Saturn 2 Z-Rail Slip-on Topper Template

I did a quick trace of the top of the Saturn 2 z-rail in anticipation of making a heater mount for the winter.   Included in addition to my final model is the freecad sketch I drew up, and the .3mf template for adding tolerance to the base design.  The final cap has an additional .4 mm added to the front and back, and .1 mm added to the left and right of the cap.  I found this gave me the snug fit that I wanted.  The ‘taller’ model will have the layer lines ‘click’ over the seam between metal pieces of the z-rail, which could either prove to hold things in tightly, or will cause it to pop out of place, depending on your fit and weight distribution, so I encourage testing your fit, or using the shorter version if you're not worried about it popping off while holding the weight of some accessory to the side.  In addition, I printed these on a ender 3 pro, .4 mm nozzle, with stock calibration, so your dimensional accuracy may vary.To be clear, the taller model is around 15mm long, and only 12 mm of that are the cutout.  At that height, it doesn't interfere with the printer.  The shorter model is 10 mm, 7 mm of it being the cutout.  The pictures show that I did these testers with zero top and bottom horizontal shells.  If you want to do more solid infill layers, you could easily reduce that 3mm ‘top-part' of the topper.
