For Toyota Engine Cover, 6mm Hole Push to lock Clip. 2 Versions of design. One on Print, One experimental. The "Straight Up" one is poor quality of my RepRap, I may do a re-work which uses 3mm filament to clip it in place. Straight up also broke its pin as I removed it from the bed. D'oh. The V2 is on print now. Try the combined STL. I will update.......Ok, this was printed successfully and is in my engine bay fine, has been for 8+ months. ....its pink. Makes it easier to see p.s. if you like this car part, why not download (or just view) the other designs I've done:20/06/2016: VW Sharan / Alhmabra Rear Adjustment Handle http://www.thingiverse.com/thing:1586975 15/01/2016: VW Sharan Trim Clip (3D Printed) http://www.thingiverse.com/thing:1274409 14/01/2016: VW Sharan Trim Clip (as Mass-produced) http://www.thingiverse.com/thing:1261167 25/10/2015: Alhambra Seat Handle http://www.thingiverse.com/thing:1092459 11/01/2015: Toyota Engine Seal Fix http://www.thingiverse.com/thing:629300 12/08/2014: Toyota Avensis Parcel Shelf Clip http://www.thingiverse.com/thing:426125 06/02/2015: Car Panel Clip (2 Versions, 4 parts!) http://www.thingiverse.com/thing:665635
