Anet A8 Fixed Bed Spacer with Cable Chain Guide

prusaprinters

This is probably not so much a remix as a recreation, but (1) I got the dimensions for the original part by moving the imported STL around in OpenSCAD and (2) I'm currently running the original parts. I plan on replacing the one at the left forward corner, though, with a guide to keep the Y-axis cable chain from getting in the way of the printhead. (The chain itself is very flexible, but the wires inside? Not so much. I probably ought to replace the bed power wiring with silicone-insulated wires.) These spacers replace the springs and thumbwheels and convert your A8 from an adjustable bed to a fixed bed. You'll probably want to at least enable manual bed leveling in Marlin, though a bed-leveling sensor and automatic bed leveling would be much more convenient. Update (16 Jan 19): the spacers were looking kinda squished when I had the bed apart to fix a flaky connector, so I reprinted them with 100% infill. The cable-chain guide is still OK, though, so I'm leaving it in. The darker green cable-chain guide is Priline green PETG printed with 40% infill; the lighter green spacers are 3D Solutech transparent-green PETG printed with 100% infill. Print Settings Printer Brand: Anet Printer: A8 Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 100% Filament: 3D Solutech PETG transparent green Notes: If you have a Y-axis cable chain, print the spacer/guide with supports, and print three spacers to go with it. Otherwise, just print four spacers (no supports needed). Since these will come in contact with the bed, you probably shouldn't use PLA. I used PETG for mine and they've held up pretty well. Support needed for the spacer with the attached chain guide arm; the others should be printable without support. Category: 3D Printer Parts
