Use these brackets to hold your Sunlu S1 FilaDryer on top of your printer, bolting onto the 20x20 aluminium. One version has a curved leg to add a M6 PTFE connector so you can use some Bowden tube as a guide. The hole is positioned Y+47mm from the centreline, which is perfect for a BIQU B1, and should work for most over printers like the Ender 3.

The PTFE connector versions have a large hole for Z rod clearance, and should be mounted directly over it. It must also be used in conjunction with a SUNLU PTFE connector such as:

For BIQU B1 users, I recommend using this in conjunction with this filament roller guide: https://www.thingiverse.com/thing:4816969

Changes made (original to V1):
-Internal chamfers made smaller so the unit seats properly.
-Pitch between recesses where the feet sit changed from 50mm to 52mm (check your unit)
-Diameter of recesses where the feet sit changed from ø16.5mm to ø17.25mm for a less critical fit.
-Shape changed for more stability.
-Cut-out for 20x20 extrusion designed at 20.30mm wide for an easy fit.
-Guide for PTFE tube.

Changes made (V1 to V2):
-Move Sunlu unit back by 47mm, so the filament has a straight path to the extruder.
-Less intrusive designs stop snagging on bowden tube when printing tall objects.
-Bolted through the front, not the top.
-Uses an M10 PC4-01 coupler so tube can go right through, meaning less drag
-Filament guide doesn't stick out to the left as far.

Please upload pictures if you make it, its nice to my designs being used :)
