I wanted to create a repository of free to use 3D designs that are in one organized place. I will do my best to update the thread as new designs are posted. One old thread was from 2020 so please be patient as I work through this and try to keep it maintained.

I want to tip my hat and credit @suchtragedy, @Camaroboy383, and all the other designers who have shared their work with the community! In my opinion this only adds another enjoyable aspect to an already fun hobby!

This is intended for people who want to install the Max6 without having to rely on double sided sticky tape to secure it.

๐Ÿ’ EC5 Connector Press (2023/03/11)

๐Ÿ’ Flysky FS-GT5 Radio Upgrades (thumb steering, menu knob rep, aux channel knob rep): https://www.thingiverse.com/thing:4647728 (@suchtragedy)
Improve the Flysky FS-GT5 radio to make it more user friendly, imo. Designs include thumb steering easy add-on, an easier to use menu knob, and Aux5/6 knobs that makes it easy to adjust with 1 finger (works great with Aux6 for rear wheel steer while driving.)

๐Ÿ’ RC Wheel Balancer (uses Arrma 6s rear hub assembly): https://www.thingiverse.com/thing:4643011 (@suchtragedy)
RC wheel balancer that basically is a stand and to it you mount an Arrma 6s rear hub with axle/bearings/hexes. With the 6s rear hub you will be able to balance 17mm hex wheels but I've also included adapters that can be quickly mounted so you can balance 12mm hex and 14mm hex wheels.

๐Ÿ’ 50cal Ammo Box Lipo Organizer Tray: https://www.thingiverse.com/thing:4615986 (@suchtragedy)
Each set of (2) trays is designed to sit in the bottom of a standard military style 50cal ammo box. The total amount of slots for a pair of trays is (8)45x60mm which should fit most 3s-6s RC car sized lipos and (4)28x60mm which fits most 2s RC car sized lipos.

๐Ÿ’ RC Body Clip Retainer/Tether: https://www.thingiverse.com/thing:4539691 (@suchtragedy)
Body clip retainer/tether to replace the stock arrma tether. There is another design on Thingiverse that is a closer replica to the stock Arrma tethers but I found it difficult to print because no matter the orientation it needed supports or the results were mixed and quality was meh. I made this as a comparable alternative and it requires zero supports.

๐Ÿ’ Hobbymate Speed H6/HOTA H6 Pro Charger Stand: https://www.thingiverse.com/thing:4484740 (@suchtragedy)
Puts the charger on it's side at a 30% upward angle so you can see the screen from across the room.

Huge thank you for putting this all together. I have tried about 5 or 6 different mud guards for my Arrma Talion and Outcast but haven't found one that fits correctly. Has anybody printed one out they liked and worked well for them?
 
I have been meaning to try a set as well. I can update the original post with user feedback or additional designs people find. One thing I am not too keen on, some mud flap designs with wording, they fill with dirt and are hard to clean.

What was wrong with them?
 
What was wrong with them?
Mainly the holes they made for them did not line up to the rear A arms. Or the one I found that did fit had a weird top layer to it. I really need to start diving into Prusa 360 or something similar.

๐Ÿ’ฏ agree. Just a good way for mud to get stuck in them. I will also update this thread with any good ones that I have tried / found. I want to make sure I can do some real world testing to see how they hold up as well.
 
Been busy printing away and testing and wanted to share a couple of prints that thought be useful.

I'm probably not the best person to ask as I just started 3D printing a couple of weeks ago but really just followed the recommended settings for my S1 Pro.

I tweaked them a little but found this worked best for me.

Temp: 205 degrees
Print Speed: 45-50mm/s
Retraction: 2mm
Retraction Speed; 40mm/s
Print Cooling: Off
Bed Temperature: 40-45 degrees

On thing I did notice when printing with TPU is it tended to lift from the print bed. @Tex Koder gave me the idea to use TabAntiWarping. That is definitely helped keep the prints adhere to the bed. Alternatively you could add a brim as well.

Another thing I did increase was the wall thickness and the top layer and bottom layer thickness on my TPU prints. For some of them I printed high as 12 walls with 12 / 12 top and bottom layers just to see how I liked it.

I will keep updating the thread if I find anymore that I enjoy / like. I hope to test the durability of these wing mounts very soon. ;)

Phenomenal. I have them on all my vehicles. Have held up great to some direct impact. I love they have 4 mounting positions as well.

Highly recommend them.

Edit: thank you again for putting in the time and effort to creating this thread.
 
@WoodiE @slick2500 would you guys mind giving me access to edit this thread? Have some updating to do. Time to add a Gorgon section! :cool:
