* Widen ball well opening in REVD BTU mod
- The ball opening had an overhang left from older versions, which
should have been removed when updating for REVC or REVD. It's now been
removed.
- The actual ball well is still smaller than the official REVD
top, but this makes it closer.
* Rebase REVD changes onto REVC BTU top
- In the previous commits I had mistakenly copied the Ploopy REVD
changes onto a REVA BTU top. This meant that the ball well was too
small if you had a REVC or REVD ball.
- Now the ball well is the REVC version, with 47mm diameter. This should
mean there's much more space for the larger ball!
- This updates the BTU top to the REV D version of the Ploopy top, which
is screwed together using self-tapping screws instead of M3 screws
with threaded inserts.
- This is untested so use at your own risk. There may be another change
brought in with REV D that I've missed, and not copied into the mod's
REV D.
* Remove V3 and V4 bearing tops based on REVA top
- The ball used in newer Ploopy trackballs doesn't fit in the REVA top -
it's just slightly too big.
- I've designed an updated BTU mod for the REVC top, which should work
fine with the older ball.
* Move README images to img/ subfolder
* Add blank REVC STEP and STL files
- These are the official Ploopy Top REVC, edited to remove the bearing
sockets.
- The idea is that these can be used for any future mods to use
different bearings.
* Add REVC versions of the BTU top STEP and STL files
* Rename v4 BTU mod FreeCAD file to match naming scheme
* Remove FreeCAD file for v4 BTU top
- It's not really relevant any more as it only works for the smaller
ball
* Add REVC BTU top mod to the README
- Also explains that the v3 and v4 ones can still be found in the commit
history
* Add files for Ploopy top without bearing sockets
- These files were created in Rhino by deleting the surfaces that made
up the bearing sockets and patching the holes that were left
- This is a good base for the BTU top or any other mods people want to
make
* Add BTU mod top piece v3
- This is the first full version of the BTU mod I created.
- v1 and v2 were just test pieces that mounted to the front screw
holes of the trackball to check clearances. They weren't really a
usable top as they didn't have anything other than the ball well.
- This part has been test printed on an Ender 3 and works well.
* Rename STEPs folder to STEP
* Add BTU mod v4
- This is a full remake compared to v3, which was designed in Rhino. To
make it more accessible for contributions, it's been redone in
FreeCAD. This means you can edit it with a free program as well as
making it parametric. The positions of the BTUs can be edited by
changing the values in the spreadsheet embedded in the CAD file.
- These parts haven't yet been test printed
* Add README for BTU mod
* Add more detail to mod README
- Print and assembly tips
- Some images to show what the mod actually is and what to cut off the
secondary buttons
* Rearrange bearing distributor list
- It didn't need to take up so many lines
- Also added Bosch's contact locator tool to make it easier for people
to find other distributors, as suggested by /u/d4baller
