Building steps
Step 1
Make base plate 800 x 400 mm out of suitable material (aluminum, wood, plastic)
Step 2
Attach M6 threads to base plate in specified locations (see CAD-files)
Step 3
Attach 125 and 134 mm clamps using the M6 nuts at specified height (see CAD-files)
Step 4
Attach 125 mm PVC pipe, flange, and 134 mm Plexiglass tube to clamps
Use PVC-tape to guarantee airtight seal between flange and tubes
Step 5
Connect PVC 90° bend and second PVC 125 mm pipe, rubber seal is present in PVC bend so PVC tape not needed
Step 6
Connect mask clamp assembly (see CAD-files) to plexiglass tube, use PVC tape to guarantee airtight seal
Step 7
Connect 32mm PVC tubing to mask clamp assembly
Step 8
Attach Air hose connectors to plexiglass tube, and to PVC 125 mm tubes. Use silicone sealant to guarantee airtight seal
