A printer designed in 36 hours.
Long story short, I didn't realize I still had time to submit things to Hack Clubs Highway event--until I had almost exactly 24 hours left. So, I made this. This monstrosity is a double hbot with a custom toolhead based on the Peopoly Lancer Long, capable of using a Bambu Labs A1 Mini build plate.
Second story slightly longer, I got some extra time when I was asked to do a re-review and decided to make a double hbot. Still the same size (roughly), but now it has twice the drive motors and triple the insanity. Hence the rename to being the Monstrosity.

note: this uses an old photo of the design, but the wiring is the same.
Thanks to the Voron team for publishing their kinematic Z mounts under the GPL license as part of the Voron Trident. This machine drew a lot of inspiration from the way the bed was used on the Trident.
The Monolith gantry by CloakedWayne was previously used in this design and a modified version of the 6mm belt tensioning system is used.
