Frame Fix for TEVO Black Widow

thingiverse

The La TEVO Black Widow is a chassis that may look impressive, but it's actually too flexible to print with acceptable quality. The chassis can deform fairly easily, which results in "ghosting" on my prints. To fix this, I decided to mount it on a 19mm medium board so it stays moveable while becoming much more rigid. The components were made with a 2mm hull and a 30% PLA filling. The stiffness is as expected. Here are the reinforcements: * 2 on the front arm * 2 on the rear arm * 1 on each lower corner of the vertical frame * 1 in each upper corner of the vertical frame * 4 for the threaded rods For the metal reinforcement, I used 10mm threaded rods that need to be determined based on your configuration. Tip: they should be slightly shorter than the foundation's depth to allow for adjustment tolerance. Here are the necessary equipment for my entire system: * 28 T-nuts * 28 M4x10 BTR screws * 4 M10 threaded rods at least 60mm long * 16 M10 locknuts (8 adjustment and 8 counter-locknuts) * 24 conical head wood screws Tip: despite this setup, you need to add metal profile reinforcements in the vertical frame's angles. My setup is not enough to reinforce deformations in that direction. Hack: Place a washing machine sound-absorbing mat under your board (for me, it was 600x640) to mute machine noises and stabilize the entire system on the table. Info: The angle between the threaded rods is 42°.
