MKS 901p Vacuum Sensor Holder Sleeve

thingiverse

This is a sleeve that allowed me to make, right away, a vacuum sensor adaptor to a flexible hose along with pipe fittings available at the local hardware store. Will likely order and replace this with a normal vacuum clamp and stainless steel hose adaptor. Or maybe not, depending on how far I can pump down with this. This sleeve keeps the sensor parallel to the pipes and provides support for applying pressure to seal an O-ring seal. I used a normal vacuum centering O-ring. Other O-rings could be pressed into service. Caution is advised to not overtighten this sensor holder as the sensor likely has a limit for how much force can be applied to the back of the body. Printed with ASA, but PLA should work just fine. Printed with 0.8mm nozzle and 0.3mm layer height, but the normal 0.4mm nozzle and other layer heights should work as well. Used Cura to slice with "Red ASA" brand filament settings. Changed bed temperature to 90C and selected Random "Z Seam Alignment". Use correct settings for the filament type you use. Hardware store plumbing parts are: 2" to 1/2" PVC pipe adaptor. 2" PVC to 2" threaded pipe adaptor. 2" to 1 1/2" PVC threaded reducer. 1/2" pipe to 1/4" hose barb.
