Oil funnel for VW Up! - Locks into place so you don't have to balance a funnel while pouring oil. 

Will 100% Fit the VAG triplets (Up!+Citigo+Mii) 

Test fitted on a VW Golf 6 TSI and will also fit this. Will likely fit a large range of VW/VAG models with the same style filler cap. 

I printed mine in PLA with 0.2 layer height 0.4mm nozzle, no supports needed. Just trim the lower part of the locking tabs after printing. (Printed on Sidewinder X1) printed fine with no supports. 

NOTICE! 

Care should be taking when attaching to car. Do NOT overtighten the funnel. Just tighten enough so it stays in place. If any of the tabs break off from overtightening you will have to face an expensive mechanics bill to get the tab out again. Do not run engine if any of the tabs break inside. 

With that aside the funnel seems plenty sturdy for normal use as long as you don't mount it like a Gorilla.
