Using Marius Hornberger dragchain as source for my chain : https://www.prusaprinters.org/prints/70839-drag-chain-with-removable-closing-brackets
I did not want to reprint/modify the large Electronics Box with the existing mod on prusaprint i made my own, which only requires a small cut in the Cover Lid for the electronics box.
Requires about 165mm space behind the electronic box.
Printlist: Using default Prusa 0.2 Speed profile. 2 walls. 20% infill.
Chainlinks x10 - Printed in PLA
Chainlink Lids x10 - Printed in PLA
ChainLink-ElecCover x1 - Printed in PLA
Chain-ElecCover-Anchor x1 - Printed in PLA
ChainLink-HeatBed x1 - Printed in PLA
Chain-MINI-heatbed-cable-cover-top x1 - Printed in PETG/ASA/ABS
Additional:
Zip-ties x5 - 2.5mm x 100mm
Tolerances are tight, but all parts are printed on my Original Prusa Mini+ with a 0.4 nozzle with PS2.4.0
UPDATE: 2023-05-11
I've uploaded an EXPERIMENTAL variant of the connectors.
One with a 30 degree and one with 45 degree bend.
Support is builtin, print large side down.
Pictures comes when finished printing those.
BEWARE
The heatbed-connector might be too tight with the X and extruder motor-cable bundle.
IT MIGHT also only be needed to use the angled connector on the electronics box to make the chain drag more sideways to allow for less space behind the printer.
IT MIGHT also require additional chain links.
Update PI-box variant:
This version needs about 185mm space behind electronicbox to fit cablechain.
Added Dove-tail and Pi-arm for the Pi-box project linked in comment.
This version needs one additional chain-link for 11 total.
Print in PETG, ABS, ASA or hight-temp material as it is close to heatbed.
Make sure it clears below your heatbed.
Uses one about 15mm M4 bolt + drop-in nut. Printable or metal for 3030-slot.
I use a M4x12 countersunk with a printed drop-in t-nut.
Included printable drop-in t-nuts for M3, M4, M5 (edited for height) from https://www.prusaprinters.org/prints/38366-drop-in-t-nut-for-3030-extrusion-fully-printable-f
Take care when routing the heatbed cable, as it is a very tight stretch and the cable-sleeve might not fully reach inside the controlbox.
This version also includes a printable and adjustable support-leg “screw” to mitigate any lever-effect from the long arm.
