tjhowse<p>I'm looking to replace the extruder on my <a href="https://howse.social/tags/Prusa" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Prusa</span></a> i3 <a href="https://howse.social/tags/reprap" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>reprap</span></a>. Almost every part of this extruder was printed on this printer. I want a replacement that can do 1.75mm filament. I don't need awesome performance, or lots of bells and whistles, just something reliable and repairable.</p><p>My shortlist is a voron stealthburner, prusa nextruder, or an E3D roto. Any suggestions?</p><p><a href="https://howse.social/tags/3dprinting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>3dprinting</span></a> <a href="https://howse.social/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>diy</span></a></p>
tjhowse<p>Sometime between my last order of 3d printer filament and now the entire world seems to have flipped to 1.75mm filament. Oldschool 2.8/3mm filament is hard to find, and only in a few colours.</p><p>I don't wanna have to rebuild my extruder and re-sleeve my hotend for 1.75mm filament, but it doesn't look like I have a choice. :(</p><p><a href="https://howse.social/tags/3dprinting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>3dprinting</span></a> <a href="https://howse.social/tags/reprap" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>reprap</span></a></p>

Davide Bucci<p>I 3D printed a few dragon eggs that work well with the red/blue silk filament that I used for the dragon a few weeks ago.

Davide Bucci<p>A recent project of mine has been to install a heated bed on my <a href="https://mastodon.sdf.org/tags/3Dprinter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>3Dprinter</span></a>. It went quite smoothly and it improved quite a lot the warping when I print <a href="https://mastodon.sdf.org/tags/PLA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PLA</span></a>. I used a solid-state relay that is kept in the bottom of the printer, inside a small box that I designed and printed myself. The results are very good! The warping is clearly reduced. It is not shown, but the wiring also contains a protection hearth wire for the aluminum plate. <a href="https://mastodon.sdf.org/tags/3Dprinting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>3Dprinting</span></a> <a href="https://mastodon.sdf.org/tags/DIY" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DIY</span></a> <a href="https://mastodon.sdf.org/tags/RepRap" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RepRap</span></a></p>

It is worth more than a new one to anyone with a brain. I got it for 2/3 of the price. It's a steal. Buy used 3d printers, it's really worth it, they are immortal.
