Features

Parametrizable

Parameters/Dimensions can be edited to your liking by downloading the .f3d file and selecting the “Change Parameter” interface in Fusion 360.

Modular

The Hitch_Cover can be easily removed and swapped out without removing or reprinting the main Hitch_Interface, saving both time and materials.

Customizable

A blank version of the Hitch_Cover is included in the .f3d and .stl files so you can add your own logo. Advertise your company, rep your favourite sports team, sky's the limit.

Instructions

Printing as-is

1. Download the 3MF file and import it into your slicer. I'm using Bambu Studio.

2. Measure the distance from the rear-edge of your hitch pin hole, to the rear face of your hitch receiver, then choose the correct Hitch_Interface file.

➡ Hitch_Interface_Short: Supports 43mm (and smaller) distances from hitch face to pin hole

➡ Hitch_Interface_Long: Supports 59mm (and smaller) distances from hitch face to pin hole

➡ Everything else: See “Modifying Parameters” section below to learn how to make a custom Hitch_Interface for your vehicle

3. If you're using Bambu Studio, my slicing settings should have carried over from the 3MF. Otherwise, review the Print Settings section to set your slicing settings accordingly, then paint the logos as needed and hit print!

Modifying Parameters before Printing

1. If your hitch face to pin distance and hitch depth aren't compatible with the Short or Long hitch receive options I provided, modify the hitch_depth and face_to_pin_dist parameters (in that order) in Fusion360 to suit your needs. You can also adjust the hitch_side_length parameter if you don't have a 2 inch hitch receiver.

2. Once you've made your changes, right-click the Hitch_Interface component in Fusion 360 and select ‘Save As Mesh’

3. Import the resulting stl file into my 3mf project in your slicer, and replace the stl's with the ones you've just created. Bambu Studio has a “Replace with STL” option in their right click context menu.

4. If you're using Bambu Studio, my slicing settings should have carried over from the 3MF. Otherwise, review the Print Settings section to set your slicing settings accordingly, then paint the logos as needed and hit print!
