16v valve and valve spring tray

thingiverse

Here's the list of parts I've made using Tinkercad: Valve Seat Holder: This part holds valve seats in place during rebuild. It has 6 holes for spring retaining clips. Valve Spring Retainer: This part retains a set of springs in order. It also has holes to attach it to the engine block. Valve Spring Guide: This part guides the valve spring into its seat. It's designed to work with the previous two parts. I'm not too familiar with Tinkercad, so if you could provide some guidance on how to upload custom files, I'd appreciate it!
