Summary

Update 4/7/2020: added cork holder, use size 9 corks (most used in commercial wine bottles), screw-down into place and secure with a pin underneath.

This is a new version of my miniVICE Miniature holder painting and hobby system.
old one: https://www.thingiverse.com/thing:2976476

This one has 4 jaws allowing support for both round and square bases in the one holder. Additionally, you no longer require the metal pins of the previous version. It is, however, only slightly harder to print, I had to use rafts to print the collets/jaws. It uses a 70mm rubber band. You could experiment with a hair elastic maybe.

More details to come with more detailed instructions.

For now, it assembles much the same way as the Y-Series version. View its detailed instructions here:

NOTE: in this version, the collets are numbered because the way in which they are installed matters. install them 1 to 4 sequentially anticlockwise or the chuck will not work

There are also several versions of the collets
small collet:

• 25mm - 40mm
• 65mm rubberband
• chuck jaws top regular

large collet:

• 45mm - 60mm
• 90mm rubberband
• chuck jaws top large

combo collet:

• 25mm - 45mm and 45mm - 60mm (hollow bases only)
• 65mm rubberband
• chuck jaws top regular

large collet v2:

• 45mm - 60mm
• 65mm rubberband
• chuck jaws top regular

combo collet v2:

• 25mm - 40mm and 45mm - 60mm
• 65mm rubberband
• chuck jaws top regular

would love feedback on these
