After failing to find a reliable 3D-printable bracket online, I designed this from scratch. Standard design rely on a plastic spring-clip lock, which is inherently fragile when FDM printed. This design solves that problem by using a rigid, split-bracket mechanism. The bracket is cut in half; when unscrewed, the halves wedge perfectly into the pillar chassis. Once the screws are tightened down, it locks into a solid, sturdy mount that won't snap under pressure or vibrate loose.
Key Features
No Spring Clips: Eliminates the weak points found in standard 3D-printed automotive brackets.
Wedge-Lock Design: The split-half design wedges securely into the factory chassis cutout.
Reverse-Mount Inserts: Designed for heat-set inserts pulling from the back of the bracket, preventing the inserts from ripping out under clamping force.
Hardware Required
Heat-Set Inserts: M4 (Holes are sized for 5.33mm through-holes). Note: Insert these from the opposite side of where the speaker screws in for maximum pull-out resistance.
Screws: M4x12mm bolts if using a foam acoustic enclosure/baffle behind the speaker. If mounting the speaker directly to the bracket without foam, use M4x10mm bolts.
Print Settings
Material: ASA or ABS/PC highly recommended to withstand high automotive cabin temperatures. (Avoid PLA/PETG).
Orientation: Print flat on the build plate.
