+Bolted build base
+=================
+
+Seeing the (little) reliability of the taped build base, I started
+using the bolted one. To make it more robust, I used both wooden
+plates (by drilling the holes in one of them).
+

+
+The whistle
+===========
+
+Using the new build base, I printed `the whistle
+<http://www.thingiverse.com/thing:1046>`_ (I actually used `the
+cleaned version <http://www.thingiverse.com/thing:1048>`_ ).
+
+It came out pretty well, but it does not actually whistle…
+
+[% WRAPPER 'figure.tt' pic='img_1017' alt="the whistle" %]
+A bit of excess filaments, but it printed.
+[% END %]
+
+[% WRAPPER 'figure.tt' pic='img_1018' alt="the mouth of the whistle" %]
+As you can see, there's a lot of "ooze", especially on the inside.
+[% END %]
+
+[% WRAPPER 'figure.tt' pic='img_1019' alt="the inside of the whistle" %]
+You can just see the "pea".
+[% END %]
+
+I should maybe study the effects of the "comb" and "oozebane" settings
+in ``skeinforge``\ …
+
+The "printruder"
+================
+
+Since the whistle came out well enough, I tried a "hard piece": the
+"`printruder <http://www.thingiverse.com/thing:958>`_", which is the
+support part of the extruder, in a printable version.
+
+I have to say that it feels like magic, seeing a printer producing its
+own replacement pieces!
+
+How did it print? Surprisingly well! I noticed almost no distortion /
+warping, even with such large pieces.
+
+[% WRAPPER 'figure.tt' pic='img_1016' alt="the pieces of the printruder" %]
+Ensemble: all the pieces of the printruder.

+Idler bracket. The "bridges" above the central hole are very thin, and
+protrude a bit, but it's not a problem: there is plenty of space, and
+the load is toward the opposite side.

+work can't cure.

+The motor bracket includes the hole for the ABS filament: the
+alignment is perfect.

+The easy part: the support for the insulator and the "hot" part of the
+extruder.
+[% END %]
+
+After printing, I cleaned the holes with a drill; I cleaned the
+filament hole by hand, with a drill bit, to avoid breaking the plastic
+around it.
+
+Now I only have to buy the required bolts and bearing, and try to use
+it.

+Base di stampa bullonata
+========================
+
+Vista la (scarsa) affidabilità della base tenuta col biadesivo, sono
+passato alla base bullonata. Per robustezza, ho usato entrambe le
+basette in legno (forandone una con un trapano).

+=============
+
+Armato della nuova base di stampa, ho stampato `il fischietto
+<http://www.thingiverse.com/thing:1046>`_ (in effetti ho usato `la

+Il "printruder"
+===============
+
+Visto che il fischietto è venuto abbastanza bene, ho provato a
+stampare un pezzo difficile: il "`printruder
+<http://www.thingiverse.com/thing:958>`_", ovvero il supporto
+dell'estrusore, in versione stampabile.
+
+Bisogna dire che ha del magico, vedere una stampante che produce i
+propri pezzi di ricambio!
+
+Come è venuto? Sorprendentemente bene! Non ho notato praticamente
+nessuna distorsione, anche se i pezzi sono piuttosto grandi.

+Il pezzo più facile: il supporto per l'isolatore e la parte "calda"

+
+Dopo la stampa, ho ripassato i fori con il trapano; il foro per il
+filo di ABS l'ho ripassato a mano, con una punta da trapano, per
+evitare di rompere la plastica intorno.
+
+Ora devo solo comprare i bulloni e il cuscinetto che mancano, e
+provare a usarlo.
