Meade ETX 90 Clutch Reapir

thingiverse

I recently acquired a ETX-90 with a computer controlled mount. I had some problems withe the DEC clutch slipping and like everyone else broke the knurled nut loose on the clutch peg. This is my take on a repair for this model of mount. I had the modify the arm by removing the existing peg and drilling out the center to allow the 3d printed peg to insert. There is a captured nut in the print to mate up with the clutch knob. I have not found the need to have to glue this repair in, it works just fine in place. Print Settings Printer: Anet A8 Rafts: Doesn't Matter Supports: Yes Infill: 100 Notes: This model imports sideways and that is the correct orientation. If you print this model with the base flat on the print bed the captive nut will shear the layers apart when you apply tension with the clutch knob. Printing it sideways takes advantage of the lateral strength of the filament. You will have to clean up the support material and sand to fit, but in the end you cant see the print, so it does not have to look pretty. Post-Printing Sand to fit
