Model base (set of three legs) is modified by adding tiny channel for letting the transparent fisher line (0.18 mm, 4. 6 kg) to pass through.
One need 60 cm of that line + 10 cm for making a loop. I suggest to use ‘Zeppelin bond’ type of knot, as it is compact (will hide in the channel) an would not slip.
Second modification is to use two short R+L screws:
They can be driven by 4mm hex Allen key in threads present in both bases. The hole is left for ~40 mm length of transparent filament (PET-G) of 1.75 mm. Both screws can be linked with that filament (first make it strait by putting it in hot water). On both ends of filament we apply a heat (well, a lighter or candle), allowing to form a blob, pressing against cold surface.
Adjustment can take few minutes and putting tension to external fisher line around table legs, both parts should be made symmetric.
However, if nylon line is not fixed to the legs, table is not stable enough. Possibly gluing it in the channels would make the deal: I admit I have no experience in handling nylon / PLA interface.
Deck itself can be taken from source project (see remix link) or can be of arbitrary surface.
Warning: before assembling the legs, please make sure that screws can be driven with enough ease in leg bases.
