Finishing off the 3D printer cabinet

There's a bit more work needed to finish off the 3d printer cabinet. This should be done as part of the extraction works so we don't have to shift everything out and in again.

Work needed - building:

•  

  Adding doors to the front of the cabinet (see subtasks below)

•  

  Adding an extra level of French cleats for spool storage

•  

  Building a trolley for the XL

•  

  Building an enclosure for the XL ( @Sophie Murday is printing the parts for this from ABS)

•  

  Routing air extraction from the trolley into the cabinet

•  

  Build trolley for the sandblaster at the same time as they'll have essentially the same design

•  

  Sanding down all exposed wood surfaces

•  

  Filling any cracks

•  

  Sealing the exposed wood

Work needed - electrical:

•  

  Replacing the relays with a better electrical solution that has an actual API ( @Penny Wood is acquiring Sonoff relays)

•  

  Bonus: Provide remote controlled GPOs for the rest of the e-lab.

•  

  Adding LAN points for the printers (and possibly the relays too)

For the doors, I am thinking the best option would be sliding doors. While opening doors on hinges were my original consideration, I feel four doors on two tracks means you can access half the cabinet easily at a time and can leave them open without risk of them being knocked off or getting broken.

Adding tracks to the existing cabinet is going to be slightly tricky, ideally the tracks would be rebated into the wood frame but this will require partial disassembly of the bench and may need some screws to be changed around. Alternatives are to just screw the tracks to the benchtop, possibly with a timber moulding around it, or make a framework for it that attaches to the front of the cabinet. The front framework would have the advantage that it potentially would look nicer, plus it gives just a bit more depth to the cabinet that way, but it is more work too. We also need to consider how to get the doors in place once built, and being able to replace doors if they get badly scratched or broken.

Work needed - doors:

•  

  Source materials (see below)

•  

  Cut acrylic for doors, including laser-cutting holes for handles

•  

  3D print flat cut-out handles for the doors and install

•  

  Install aluminium frame around doors

•  

  Figure out and install tracks in doors

•  

  Place doors into tracks

•  

  May need to add supports for the benchtop in the centre

Inventory of parts required

•  

  More 75x30 framing pine. There is some left over but probably not enough.

•  

  DAR 42x19x3m x2 (French Cleats)

•  

  Heavy-duty and lockable caster wheels x8 (may be able to salvage 4 from broken trolley)

•  

  Heavy-duty wood sealing. I have used carbothane clear a lot in the past with good results

•  

  Painting equipment and solvent for cleanup

•  

  Acrylic panels for doors - Penny to measure doors.

•  

  Aluminium c-channel frame for the doors

•  

  Aluminium track for the doors to run through - possibly with ball-bearings for easy slide

•  

  Relays, we discussed this and think the Sonoff 4ch pro are the best in terms of price and ease of use

•  

  Ethernet switch and cabling (I suspect a 100kps switch is probs plenty, GB upstream though)

•  

  Ethernet wall plates x4
