+Solvespace models
+=================
+
+This is a collection of my custom-made 3D models, with some commentary.
+
+Bathtub strainer
+----------------
+The first thing I've ever modelled for printing, hence the simple geometry.

+
+Cable hooks
+-----------
+To be glued to a desk using

+Prone to delaminating under load when the printer is badly tuned.

+
+Geiger stick
+------------
+For https://www.aliexpress.com/item/33058301946.html[Huahe M4011] and
+a specific diameter of aluminium pipe.  Use at least three perimeters for
+the handle.

+
+Book scanning stand
+-------------------
+The pitch of 7 cm fits Samsung Galaxy Note 20 Ultra.  Not as useful as expected,
+however the idea of using aluminium pipes has turned out to be a good one.

+
+Paper boxes
+-----------
+These are actually 2D models for making closable little containers out of
+folded-up paper and a few drops of glue.  It takes a lot of time to make these,
+so not recommended.

+
+Pill container
+--------------
+This is not a particularly good design, and the tolerances are somehow off,
+so I failed to have it work after reprinting on a different machine.
+Large pills can be very difficult to extract.

+
+Strainer adapter
+----------------
+Fixating a pretty stainless steel strainer in my slightly incompatible sink
+drain.

+
+Trivial Kailh Choc keycap
+-------------------------
+Fast to print and perfectly functional in PLA, though obviously not very
+comfortable, nor nice to look at.
