Fixed and reuploaded ALL the models with clearance for the new filament sensor for the QIDI BOX. Also increased clearance of the part right below the filament cutter, to allow easier removal. Thanks to the user that warned me :)
New designs added: FACES. You will find them in the new folder “Faces front covers”. It is now quite some work to make all the various combinations of designs, so I only uploaded a single combination for each face type. Feel free to ask if you want a specific combination, I will upload it for you!
UPDATE 06/11/2025
Added the models for my new improved cooling fan housing for replacing the stock fan with others (or a honeybadger like I did) - both regular and wide mouth (please refer to the housing model page for details)
They are in the new folder “Improved cooling fan housing…" and fully compatible with the rest of the designs or the stock parts!
I think the results are worth checking it out, not bad for a 10$ upgrade!
Be aware that you will likely have to retune your fan speeds for certain work, depending on the power of the new fan. If I find a general “rule” I will make sure to update :)
The covers of the Q2's toolhead are pretty easy to remove and replace, no need to unplug any cables, you only need 2 allen keys.
For the front cover and the cooling fan housing you will need some magnets, I used N52 Ø4x4mm magnets.
Always remember to check for the correct polarity before you glue them! You don't want to glue them and see your cover is getting pushed out when you try to put it on, ask me how I know :)
The hotend fan housing is pretty straight forward: you can remove the two screws holding it and it will slide out from the front. You can then remove the two screws holding the fan to the case and replace it. I wanted to put heated inserts instead of having the screws work in the plastic, but it has been just fine so far.
While the hotend fan is hanging, you can access the two front screws that, together with other two screws in the back, hold the cooling fan housing. Once the screws are removed, you can access the other 2 screws that hold the fan and the lid of the housing. Remove those and replace them with the printed parts :)
I suggest printing with PETG as a minimum or any other filaments with higher temp resistance.
It's worth to print the Lid in ASA or better, especially if you print high temp technical materials. PETG seemed fine for basic materials like PLA but I don't suggest it at all. There is risk of it collapsing and hit your prints or your machine.. ask me how I know ;) I use one printed in PBT pro now and it's ok. Still, consider the best you can get if you work at very high temps.
If you want to be extra sure, use the original lid or print with higher tier materials with very high deflection point.
Please BE CAREFUL!!! It doesnt take much deflection to hit these points at the top of the z screws!!
The pieces are pretty easy to print with no special attention needed, but I will include project files with each set so that you are able to see the way I printed them with manual supports. If you have troubles consider printing each piece separately, especially the hex or ghost versions.
I know it looks weird, but I honestly like the cooling fan housing printed this way:
It will only use 1 more gram in supports but the pocket for the lid will be printed much better making it sit flat.
Just be careful when removing supports not to break the parts for the screws… another “ask me how I know” :' )
Feel free to ask if you need help or if you want me to make a specific design! Also share your makes, I love to see more fancy Q2s :)
