Mingda Magician Series - Extruder Tensioning Screw … Original - hate/hate relationship. Screw too short , head diameter too small - makes installing with filament already loaded nearly impossible (for me) to screw in. Added retainer washer to captivate knob assy (improved quality of life !). No more hate/hate relationship. https://imgur.com/a/cG6NK2c

Here's an even larger knob if you need one !!

V4 - Print this part and screw in a m3 x 30mm socket head cap screw into a recessed m3 hex nut, add 2 additional m3 hex nuts,  and reuse original spring and washer. 

V3 - Print this part and screw in a m3 x 25mm socket head cap screw, and reuse original spring and washer.

Revision History - 

Updated 10/27/22 

  • Retaining Washer V2 - revised to be larger and thinner. Just seems to work better for me.

Updated 10/26/22 

  • Knob V4 - redesigned to accept m3 nut recessed on back side to prevent screw from spinning in knob. Uses 30mm long screw, so 2 additional m3 nuts required for appropriate length  of thread.

Updated 7/7/22 

  • Knob V3 - design style like Y belt tension knob, made 0.5 mm thinner (difference on screw head side)
  • Retaining Washer V1 - New

Updated 5/31/22 

  • Knob V2 - larger diameter, tighter fit on screw.
