Yolco GCX37 Legs for VW T6/T6.1 Rails

This is version 1 of my take on fixing the Yolco GCX37 to the floor of our California. 

The legs are quite bulky because I wanted large security margin for fully loaded fridge. All printed in PETG and I recommend keeping it out of reach of the heater exhaust. 

For each leg you will need:

• 4x M5 60mm Hex Head Bolts
• 4x M5 55mm Hex Head Bolts
• 8x M5 nuts
• 1x M8 T-shaped screw with nut that fits the rail system*

The leg assembly is as easy as to remove supports, put the nuts in, put the screws in and tighten them. 

Some time ago I ordered M8 T-shaped screws from aliexpress - they turn out to be a bit too large in diameter to perfectly fit in the rail grooves but once they are tightened they lock in and stay locked. I strongly recommend to order M6 screws there, the groove in the rail is roughly up to 6mm in diameter so M6 should work. Look for the diameter of the top of the T.

Securing each leg to the rail is the most tedious part. You need to align the T, push it down then rotate 90 degree and secure with the nut. The leg has a hole to finger tighten the nut. I used plastic knob with threaded insert also from Aliexpress and it works fine.

Version 2 might come in later as I am not happy with how long it takes to fix this to the floor + it is hard to move around too.

The holes in the legs are for possible future leg extensions - you print 8 outer legs and then connect them with 4 inner legs (not yet included)- that should lift the fridge even higher. Secure them with M8 bolts.

If you want the fridge higher, print 8 legs in total and 4 inner legs. Attach half legs to brackets and the other half to the base plates. Join using inner legs. Secure inner legs with additional M8 Bolts. 

When printing inner legs I used prusa slicer's cut tool and snap joints. I did that so that I could print inner legs on the narrow side - so the whole structure would be stronger in the contact places ( so it resists forces in the car while breaking/acc better )

I only slightly modified these
