## Customer Reviews

### ⭐⭐⭐⭐⭐ While for a Mk7 E3D head, this works for a MP MiniDelta and related hotend as well.
*by M***T on March 3, 2021*

Just what the doctor ordered for my worn out heat break. (The teflon does get a bit off and you get crud still stuck in the thing after a long amount of use...) This is a one-for-one replacement without doing mods to your MP Mini-Delta's heat break. Just pull apart the hotend with your tools you got for maintenance with the printer and re-assemble with one of these gems instead. Good to go.Knowing what I know about my printer, this should do well with any 30mm configuration with the short threading at the hotend side of the heatbreak and a smooth bowden end.

### ⭐⭐⭐⭐⭐ Great upgrade from threaded types
*by K***N on September 30, 2018*

Lovely replacements for threaded type! I drill out the threads on the original extruders and tap a set for the shafts. This allows for fast and quick leveling and and matching nozzles for duel or multi extrusion printers. The shorter shaft allows room for printing on glass beds due to the extra thickness of the glass

### ⭐⭐⭐⭐ Pretty good
*by D***H on June 24, 2019*

3 of the 4 were great. One of them had a slightly off smaller diameter hole drilled, the hole above the PTFE tubing. That hole being off caused some underextrusion. Will likely still buy these again because they still work well.
