Description
I've been printing more ASA and ABS, and lately venturing into PC. On top of maintaining chamber temperature, having a good seal to reduce VOC gas escaping into the printing room is important.
The Problem
The rear betweener has a gap for the hot-end cable and Bowden tube and it doesn't really match up with the edge of the Creality K1/K1C lid, working against the idea of sealing in heat and VOC.
The Solution
It is actually quite straight-forward,
Thicken the rear betweener so that it matches up with the edges of the Creality K1/K1C lid
Reduce the size of the gap for the Bowden tube and smooth the edges so that it doesn't wear out the exterior of the Bowden tube when it shifts (slightly) during prints
Seal the portion blocked by the hot-end cable
However, modelling it in TinkerCad is actually more complex.
I did it so that you don't have to.
How I printed it
Material: ASA
Perimeters: 3
Top and bottom layers: 3
Fill: 20% Gyroid
Supports: Yes. Tree (manual) - Paint the overhanging part for the hot-end cable
