The model is designed for my Renault Kangoo, but with small adjustments to the edge mounting brackets, it should fit almost any vehicle.
Right now, I’m working on the next generation (V3) of the bike holder. The goal is to improve how it handles the bike axle angle and to make it a bit more flexible with bike orientation. That said, I’m not fully satisfied with the current state yet 😉.
The V2 holder, however, has been in use for several years and works reliably.
Needed Parts
2x aluminum extrusions 30x30 (your preferred width) (earlier I also used 2 smaller extrusions in between, but they turned out unnecessary)
2x M8 screws for the corner brackets
M6x12 screws + T-nuts
4x to mount the extrusions to the corner brackets
4x for each bike holder
M5 heatset inserts (for the bike holder)
Axle of the V3 holder
M5 screws in different lengths
Printing
I tried to make the parts as easy to print as possible, but a few spots still require supports. Everything should be printed in PETG or similar material.
Bike holder: print standing. The base has increased infill for better strength.
V3 axle: I added a modifier so this area prints with 100% infill, giving the heatset inserts more grip.
Assembly
Its pretty straigt forward:
Base
The base is simple screwd together (as mention before, in the beginning I had additional parts, but now just the printed elements)
In my car I screw the base to hole of the lashing points
Bike Holder
Add heatset inserts wherever you need them (or everywhere 😉).
Most inserts are designed to be melted in from the bottom, except the front ones, which go in from the top.
Tolerances are quite tight, so assemble the levers and move them a bit before inserting them into the holder.
The end holes can be tightened or left a little loose, depending on preference. I keep mine slightly loose so the holder moves but doesn’t wobble.
Bike Mount
The V2 holder can simply be screwed down and used.
The V3 axle requires heatset inserts, which are inserted from the front.
