Hi,
On the subject of vacuum forming, I made a simple vacuum former to make a plastic tray for my daughters school project when the schools vacuum former was not large enough. It was really quite simple but surprisingly effective. It basically consists of a box (I used MDF top and bottom and a square timber frame) with an outlet to connect to the vacuum cleaner. The silver foil tape you can see is to keep the box air tight, and the brown strip is draught excluder to form a seal. The mould you can see is over a couple of 50mm holes. Drill series of small holes around the periphery, and anywhere you want the plastic to pull into, particuarly internal corners:

Then we fixed the plastic sheet to an MDF frame as shown below. We got the sheet from a school supplier, they sell packs of vac form plastic sheets – was only a few pounds for a few sheets, and was the only thing we bought:-

Then, (waiting until the coast was clear) heated the plastic on the frame under the grill, then when compliant, quickly placed the frame over the mould and switched on the vacuum:

Allow to cool, remove and trim. Was quite a fun excercise and only thing we bought was the plastic sheets. Could do something similar for tool trays..?
