MP3DP Repeat H2 Build

This is just the hotend, but I recycled most of the parts from my MP3DP V2 H2 hotend. I also created the Part Cooling fan duct to more properly fit the origial and V2 versions of the H2 Hotend. Shown is the 4020R version, but I also have a 5015R and 5020C versions as well (but not real world tested yet.

See attached pics and assembly diagram.

Wow, talk about Cad Skills, love that drawing!


Thanks! I’m an aerospace engineer by trade…lol…


Hey Ryan, I think I know someone who can help with Drawings and Instructions for the LR3, just sayin, LOL @Ryan


Heck yes!

I will probably do a few exploded views this time around. I will get the basics up and let’s see where we can go from there!


If you need techpubs, i can probably lend a hand. plus id love to take a look at the next iteration that i can take my lowrider to…lol


Nice, Thanks!


Dude, this is awesome. I have been dead set on progressing with my Repeat this weekend, starting with a new tool mount. Unfortunately, my CAD-fu is straight garbage. Printing this now. Thank you.

No problem! Glad I could help. I’m building my repeat now, just waiting on parts.

Hey just wanted to give you a bit of feedback on the H2 extruded mount. Everything is working great. Cooling is working well with your fan mount. Although it’s great as it stands now, if I were to change anything about it, it would be to move everything over to the right a few mm to try and flush the bltouch with the left side of the hub so that there is no potential interference with the end stop.

I was, however, able to get by just fine with my build, but I could see it being a potential issue with certain setups.

Thank you again for those files. They printed very well and are functioning great.


I had to pause my Repeat build as work got hectic. I did however see that as a potental issue and made the BLTouch mount more shallow to clear everthing to the right, but have yet to release the updated files. I also adjusted the the main H2 body mount since it sometimes bends the fan part of the H2 body mount. I also made that part a tad thicker for printability issues (it sometimes fails when printing the outermost part of the fan arm where its basically 1.5mm^2).

Thank you for the feedback, and I welcome more if you find anything else inadequate!


This is the best community :heart: i have ever been involved in. I wish the world did to


Any chance I could get a modification on your cooling fan mount for the REVO version of the H2?

I dont have a REVO version of the H2, and I’m still rocking a Repeat. I can probably give it a chance… what Fan size are you looking for?

same fan, just move the output of the duct over and down a little.

@azab2c posted this a while back.

Firstly, I appreciate MJLeverty sharing their MP3DP "Repeat" Toolhead, BIQU H2 by inoxdragoon - Thingiverse, thank you!

Since it’s been a while… Curious what other Part Cooling Fan Ducts designs folks are using on their BIQU V2 H2, for a REVO version ideally, but mount points for regular are not too different.

There’s a bunch on Printables, am wading through those options. BTT have one on GitHub too, H2 V2s Revo >> H2 V2S Revo 4020 fan duct.STL. However suggestions from folks here carries more weight for me. Cheers!
