Malkus Right sided Sunlu S2 filament dryer stand

Holder made to fit right side of the printer.

This is a mounting bracket for the Sunlu S2 filament dryer. It is compatible with use of a poop bucket on the back side. Its stable with its support legs and has good clearance for the power cable. The dryer can be secured to the bracket by replacing two externally mounted screws of the dryer and mounting new longer ones through the holding tray. The legs are printed seperatly and slided into place.

1, Print and remove supports. Take extra care scraping and clearing the tracks for the legs interface. Support in the screw holes can be punched out from the sop side afterwards

2, Remove the two visible screws from the bottom of the dryer

3, Fasten the dryer through the tray screw holes from below with 2 pcs #6 x 3/4” metal screws or 4x25mm ones.

4, Tap the legs in place with some mechanical empathy (tight fit intentional)

5, Release AMS cable and existing stock spool holder if mounted

6, Fit the power cable to the filament dryer.

7, Fasten the bracket using the same mouning holes as for the filament buffer but using at least 4 mm longer screw and the other matching hole for the rear panel also with a longer screw. (I dont recommend to dremmel out material to make stock screws fit. There will be very little material left then and might be a risk over time)

8, Reconnect the AMS cably through the bracket hole

9, Fit a long PTFE tube through one of the top holes in the dryer lid and route it to your Y splitter or direct feed to the printer. I preferr using the rear facing hole because it provides a smooth bending route to the printer. Route it smoothly throught the printed bracket over the filament buffer. Make sure it is long enought to open the dryer lid without removing the tube.

My PTFE tube has an outer diameter of 4.23mm and it makes a perfect smooth fit of the tube through the small rubber bushing in the filament hole of the dryer lid. Some qualities of tubes have small OD, about 4 mm. If this is the case one might try 2 turns of tape around the tube where it enters the dryer to increase the tube diamteer or exchange the PTFE tube for a qulaity with better fit.

It is of course possible to add extra stabillity applying thin foamed double sided tape to the interface between the holder bracket and the printer panel. I preferr 3M VHB tapes with any thickness below 1mm. It will be mega strong and if one needs to remove it it wont separate having to scrape clean both sides

Feature releases might get small markings where to put strips.
