This is an Apple AirTag holder that is print in place. No assembly required! It is designed using an AirTag model based upon Apple's dimensions of 31.9mm X 8mm and photos available since the announcement.

This has been successfully printed and tested using a 0.1mm layer height. A 0.15mm layer height should also work.

For those who may not be familiar with the Hero Me…

Here is a link to the latest install and review of the Hero Me Gen7 by TeachingTech! (Starts at the 4 minute mark).
[https://www.youtube.com/embed/UAg3KpmbFLE?start=239](https://www.youtube.com/embed/UAg3KpmbFLE?start=239)

The Hero Me is a modular printhead platform for 3D printers with excellent part cooling and the most compatibility across 3D printers, hot-ends, extruders, ABLs, and other components.



The Hero Me Gen7 is all about personal preference & performance cooling. If you have been upgrading your 3D printer, you've made choices about what is important to you. Your choices are likely to be different from other makers. When choosing a hot-end, extruder, and ABL combo (not to mention fans, accelerometers, and other printhead components), where are you going to find a printhead platform that will accommodate all your selected components (which could be a rare combo) for your specific 3D printer AND provides part cooling that gives you great print results. This is what the Hero Me Gen7 is all about!



Think of the Hero Me platform as Lego blocks for printheads, there is a single mounting part for each component (hot-end, extruder, fans, ABLs, etc.) that stack and mount to the core Her Me Base. Component-specific mounting parts can be interchanged for another of the same type. So, should you change your component selection(s) in the future, you do not have to start over, you simply replace the single STL mount that is matched to the new component. There is no need to yet again go looking for a new set of mounting hardware that was not likely to have been designed to work with each other in the first place.



So to give you choices and fulfill your personal preferences in 3D printing, the Hero Me Gen7.4 now supports over 115 3D Printer models (plus clones), 47 Hotends, 37 Extruders (over 45 mount options), 20 ABL Sensors (34 mount options), 35 Part Cooling Duct options, 12 Cable Management options, 14 ADXL345 mounts, and 4 LED bar mounts (among many other options). 



If you know your 3D printer model, hotend, fans, and optionally an extruder, ABL sensor, ADXL345 accelerometer (for Klipper), and any other options for your printhead assembly, you can scan through the Hero Me Gen7 Release 4 folder, or use the Thangs Advanced Search.  Be sure to set the creator filter to: ‘MediaMan3D’ then search for ‘HMG7’ which should bring up all the STLs. You can refine your search from there by component, brand, etc.



If you find that you have a 3D printer model or component that is not yet supported, send me information and preferably a STEP or STL (or link) if you know of one for the X carriage of that printer or the component and I will create a mount for it. Send to: **[MediaMan3D@gmail.com](mailto:MediaMan3D@gmail.com)**



The Hero Me Gen7.4 folder of STLs on Thangs is organized into sub-folders by component category, with sub—sub-folders for type and brand with well-defined filenames to make it easy to find what you need. 



But If you want documentation to help you select and assemble the Hero Me Gen7 for your specific 3D printer, you can get a membership plan here on Thangs. 



By becoming a member you will get a detailed 56-page parts selection and illustrated assembly guide along with assembly videos, private Discord server access (with over 2,000 Hero Me users), technical support, and much more, You also get exclusive access to new STL releases 30 days before being posted to Thangs, and other STL libraries.

**This STL is an example of a completed Hero Me Gen7 printhead mounted to the X carriage of a 3D printer.**

Hero Me Gen7 is a modular printhead platform for 3D printers with excellent part cooling and the most compatibility across printers, hotends, extruders, ABLs, and other components.

 The Hero Me Gen7 is all about choice and personal preference. If you have been upgrading your 3D printer, you've made choices about what is important to you, Your choices are likely going to be different from everyone else. When choosing a hotend, extruder, and ABL combo (not to mention fans and accelerometers), where are you going to find a printhead platform that will accommodate all your selected components (which could be a rare combo), for your specific 3D printer AND provides part cooling that gives you great print results. **This is what the Hero Me Gen7 is all about!**

There is no need to yet again go looking for a new set of mounting hardware that was not likely to have been designed to work with each other in the first place.

So to give you choice and fulfill your personal preferences in 3D printing, the Hero Me Gen7.3.2 now supports over 100 3D Printer models (plus clones), 46 Hotends, 34 Extruders (over 45 mount options), 17 ABL Sensors (34 mount options), 35 Part Cooling Duct options, 12 Cable Management options, 11 ADXL345 mounts, and 4 LED bar mounts (among many other options).

Hero Me Gen7 Example Model 1.stl

**Update IV 12-31-23:**  Corrected the size of the central spindle hole on all versions to match the Bambu Lab original STLs. Current versions are V3 and V7. The slightly increased diameter allows my spools to proplerly fit on the excellent V-Spooler from **Fryby Additive**.

https://makerworld.com/en/models/98832
and
https://www.printables.com/model/684376

**Update III 11-19-22**:  Added a remaining filament measurement marks. These .2kg marks match the positions that Bambu Lab has on their spools. Even so, these are estimates at best.

 Added to the following STLs:
Bambu Lab Reusable Spool Remix Four-Short-V6.stl
Bambu Lab Reusable Spool Remix Four-Tall-V6.stl
Bambu Lab Reusable Spool Hex Snowflake Tall - label v2.st

Do not use ‘adaptive layer height’ as that will flatten these marks and numbers out.

UPDATE II 10-24-22: Corrected Tall Snowflake side to have proper pattern alignment with short side (cosmetic correction). Provided two versions of the Tall Snowflake half. One with label space, one without.

UPDATE II 9-30-22: Added lightweight ‘Snowflake’ version of the Spool!

UPDATE 9-30-22: Corrected missing alignment tab on tall half of the spool. Cleaned up other minor imperfections on both halves. Set the spool diameter to 200mm to match that of the Bambu Lab versions.  Added the bambulab_spool_spacing_shim.stl (print two). Current is V5.

UPDATE 9-27-22: Based upon feedback I have decreased the diameter of the center spindles to match those of other Bambu Lab reusable spools.

UPDATE 9-14-22: I have repaired the short side to be a more manageable size (was 9MB).

I have combined the best features (in my opinion) of the three previous remixes.

I started with the refactored “Bambu X1 Re-Usable Spool” as a base, then added the best features of the “Improved Bambu Lab Reusable Spool Holder” (everything except the heavier hex pattern), both of which were remixed from “Bambu Lab Reusable Spool Holder Hex Remix”.

I added an additional label space on the other spool half. I like to have both sides labeled, (trust me it saves time). I also tilted the 6 pairs of holes all around the rim at 45deg to make it easier to secure the loose filament end (and not crimp it so you end up trimming it off later).

The shim STL is the one from BambuLab's original. Print two.

Bambu Lab Filament Spool - Hex Snowflake

Bambu Lab Reusable Spool Hex Snowflake Tall - no label v3.stl

Bambu Lab Reusable Spool Hex Sowflake Tall - label v3.stl

Bambu Lab Reusable Spool Snowflake Short - label v3.stl

bambu-lab-reusable-spool-remix-four-short-v7.stl

bambu-lab-reusable-spool-remix-four-tall-v7.stl

bambulab_spool_spacing_shim-with-support.stl

bambulab_spool_spacing_shim.stl

I create designs to improve 3D printing, including the Hero Me series, an advanced printhead platform & cooling system, greatly improving print quality for 3D printers.
