Subspace Tripmine
My son asked me to print a subspace tripmine from Roblox but none of the published models were in a state to be printed without supports. I designed this from scratch in Fusion so the individual components could be easily printed without supports. The central star can also be suspended with black thread to make it appear to float.
The STL files are ready to print. The 3MF files are included in case you want to do your own modifications or a beam without holes. (Reduce the 3MF files to 75% to match the STL file sizes.)
I manually added a hole to 2 of the beams with a 1.5mm negative volume cylinder which allows the star to be supported with some black thread. You don't have to do this and can just loop the line over the beams.
Printing and Assembly:
Beam - Print 12x
Option: Add a 1.5mm x 20mm negative volume cylinder midway on one edge for a convenient hole to thread fishing line on 2x of these if you want.Diamond - Print 8x
Orientation doesn't matter.Star - Print 1x
Cut the model along it's midpoint and place cut-side down to print without supports
The beams will fit in the diamond corners as-is if your printer is well tuned. You might need to reduce them very slightly if using something other than PLA.
The star has a tapered hole on one tip to allow for black thread or fishing line to be suspended from 2 of the beams to create the illusion of the star floating in the center of the model. If you add a hole to the beams with a negative cylinder it allows for the effect shown in the picture.
Glue the star together with something like E6000 and wrap it up with some rubber bands while the glue sets. Very little glue is needed and any excess can be rubbed/peeled off the PLA when dry.
Material used:
inland Matte black PLA (0.2mm layers)
inland True Red PLA (0.2mm layers)
black cotton thread
E6000 glue
