Tantillus Reborn Build!
I started building a new 3d printer. The design is called the Tantillus Reborn, it’s a design by Toolson. More information, as well as a build guide, can be found on their blog.
The Tantillus is a pretty well designed 3D printer. The frame is meant to be cut out of 5mm acrylic, though someone published files for 1/4” material, so I used a laser cutter to cut it out of 1/4” baltic birch plywood. It’s not as dimensionally stable as acrylic, but it’s much less prone to cracking. Unfortunately, since it’s wood, it’s not quite the same all the way through, so the laser had a little difficulty cutting consistently in some locations. For this, I used an exacto knife to assist the cuts to get the parts out. The notable parts I’m using are the following:
- An E3D Titan extruder
- A Merlin V1 hotend (mine happens to be from RepRapDiscount)
- Igus bushings and aluminum rods instead of brass bushings and steel rods (I hope this works out)
- TMC2208 SilentStepStick stepper drivers
- An underwhelming MKS GEN 1.4
- A cute little heated bed from OpenBuilds
I plan to try to make a spring steel and PEI bed to fit on the heater. The bed heater gets a layer of silicone on the bottom to keep the thermistor and power leads in place. I figure I can attach the magnets to the bed during this process by immersing high temperature neodymium magnets in the silicone. The original design involves using a specialty (difficult to acquire) magnetic sheet with adhesive on the back. I hope the thickness of the bed heater won’t prevent the steel from being attracted to the magnets.
