Super DIY SnapMaker U1 180degree door hinge

yet another U1 Door hinge to open the door 180 degree

• larger and stronger hinge part, fits the printer case better

• using heat insert instead of screw into plastic part in some other hinge design.

• better door mount to fit the door's shape to block air.

• smaller door mount part to save material

• no tpu part or silicon washer needed

• two types of hinges to choose, screw from outside toward inside printer or the other way

I think type B is better, screw head is outside of the door, so it looks better.

but you can choose A or B.

no TPU part or the snapmaker U1 's original silicon ring / washer is needed, in case you lose it.

Glass door is some what fragile and dangerous. handle with care, don't break it,

currently it's not available to buy.

Hard Requirement:

Must use the original hinge's small head black screw X 2,  it has a smaller head diameter of 4.45mm and length 10mm, it was holding the original metal hinge on the U1 case..

Part needed:

M3 heat inserts

M3 screws 12mm, 16mm

optional: foam tape 3mm thick 15mm wide to better seal door edge.

Type A

  Special requirement for type A thin head 12mm screws X 4, the screw head thickness should be about 1mm. If you have it, you know what that is, if you dont know what that is, you probably don't have it. So do not choose type A option.

Type B

 when adding heat insert into inner door mount part, do not put the part directly on table on its ring, because the heat will make the ring deform under force.  put its main body on something to do it, so the ring is not under force.

Print Setting

stronger the better, especially the door hinge part, the glass door is heavy.

5 wall and infill 50% up.

no support

Using PETG or ABS for chamber heat.

Assembly

in general, do not tighten the screw too hard, we are dealing with glass.

check pictures (type B is shown)

1. Remove the door from the printer, handle with care. Use the original metal hinge part to rotate the door hinge mount base to 90degree ( the U1 door can only open 90degree originally)

2. When choose type B:  add heat insert to :  u1_hing_low.STL , u1_door_mount_top_typeB ,  2X_door_inner_mount_typeB ( 2X meaning need 2 of this part)

3. When choose type A: u1_hing_low.STL , u1_door_mount_top_typeA and u1_door_mount_bottom_typeA

4. Use the original hinge small head black screwX2 to install u1_hing_low.STL and u1_hing_top.STL in printer case. Must use the small head screw (Dia about 4.45mm) otherwise if using a normal M3 socket hex screw the head is about 5.6MM, the glass door will hit it and cause a disaster.

5. hold the door in your hand and sit down somewhere comfortable, add door mount part (type A or type B) to door. door mount part has TOP or LOW printed on the back, should not be put in wrong place. use 2X M3 12mm screw each top/low. 

• For type A, Must use thin flat head screw only (screw head is 1mm thick), as between glass door and printer case, there is not much space left. if use normal screw the door cannot close or you could crack the glass.  put screw from inner mount part and pass glass to the door mount part.

• For type B, put the M3 12mm screw from outside part through glass door hole to inner door mount part.  Check picture.

• after install top and bottom door mount parts, put the door in printer in place. use two M3 16mm screw to put the door to printer/hinge platform. be careful not to hit the black hinge screw with glass. 

• after door is installed, very slowly open a little bit and check the glass is NOT touching the small head black hinge screw.

Optional 1: use a foam tape to seal the big gap on left vertical edge, 15mm wide, 3mm thick (check picture).

Optional 2: use thinner foam to seal the whole door's edge
