R8 Collet holder

Simple remix of Winegummo's design. I found the collets slide out the front when opening the drawer. Added front stop and narrowed the back a bit. Went with 5x combined into single as that's about the largest (widest) print my Rostock will handle, also really only own 5 R8 collets right now so it kind of lined up.

If you print with support (bottom is sloped) you'll get better top finish. It's a tool holder that will be covered in swarf and oil soon enough so I decided to use "lay flat" in Repetier to avoid support. Given top is no longer flat that way it has a steps that show in finish. Honestly looks worse in photo than it actually is.

Update Jan 2022: Added sizes to trays (will need multi material/dual colour printer) and leveled better. No support needed.
