About Downloads

As a hobby, I designed and modeled all of the downloads myself. All downloads are free (except the ones that link to 3rd-party sites) to do with as you wish. Check back every once in a while to see if I've added more downloads. If you sign the guestbook, I may send out emails if I have a download I think people may be interested in. Don't worry, I don't like email SPAM either!

MY NOTES ON 3D PRINTING

Don't use PLA filament for anything structural, that may be subjected to impacts, or that will be exposed to grease, oils or solvents. I noted the ones below that are ok to print with PLA.

There are a lot of 3D filaments types, and I have only tried a few. I have found that PBT-Pro filament (CC3D PBT Pro Filament) excellent for all most of the models I have created below. It offers some flexibility to take impacts and is strong. It is resistant to oils, greases, and most solvents.

Makes putting the roll cage on a bit easier.

This holds a lot of tools! 200mm x 200mm

Custom Fit 2025 Hustler Pit Stand With Shock Holders (.STL file for 3D printing). NOTE: Regular PLA filament will work fine for this part.

This fits 2025 GFRP Hustler. Chassis fits in snuggly so no falling off when moving around. Great for displaying vehicle too.

Fluid Tray (.STL file for 3D printing) used for changing shock oil, cleaning parts, etc. Holds fluid until you can despose of later. Don't print out of PLA. PLA is not resistant to oils and solvents.

GFRP Front Sway Bar Mount Spacer (.STL file for 3D printing). NOTE: Regular PLA filament will work fine for this part.

The GFRP sway bar is poorly implemented in my opinion. I was not comfortable with they way it installed with only the included parts - binding, limited movement, and interfered with the body. It seemed like an afterthought. These spacers make the fit much better. NOTE: For the spacers to fit, you will need 4 3mmx16mm screws. The screws included in the GFRP sway bar kit are too short to use with these spacers. If you need the screws, save yourself some money and buy a kit of them on Amazon.

Easy Swap Motor Holder for Motor Analyzers (.STL file for 3D printing). NOTE: Regular PLA filament will work fine for this part.

If you've ever used the SkyRC Brushless Motor Analyzer, you know what a pain it can be to attached the leads to the motor with the bulky aligator clips. This easy swap motor holder allows you to quickly and easily pop the motor in and out between adjustments. Now, I acutally don't mind using the motor analyzer.

There are several parts you will need to complete the holder like in the pictures below. Unfortunately, you can't buy the exact quanity you need, so you will have to buy in bulk, but the good news is that you will be able to make several of these and have a lot of screws and nuts left over for your RC toolbox. Total cost for parts is ~$45, but it's cheaper that buying a single premade one, and you can give a couple away as Christmas gifts!

Parts (Amazon links):

Modular Toe Angle Guide (.STL file for 3D printing). NOTE: Regular PLA filament will work fine for this part.

No more fiddling and measuring toe angles. Snap in the toe angle you want, adjust the base width to the vehicle width and set your vehicle toe. Easy! You can even set the toe angle of individual tires, e.g., you can set the right toe to +3 degrees and the left toe to -1 degree. Comes with 6 sets of toe angles (+3, +2, +1, 0, -1 and -2).

Maximum vehicle width with tires on: 365mm. Minimum vehicle width with tires on: 223mm.

Tabbed Battery Holder for GFRP Vehicles (.STL file for 3D printing) NOTE: Regular PLA filament with 100% infill should work fine for these parts.

You will need 2 - 3mm screws. Depending on the size posts you use for the battery, you will need 20mm or 25mm length. Do yourself a favor and buy screws cheaper on Amazon: 1,000PCS M3 Button Head Screw Kit
