DIY Dive Gate:
For a 2x2m gate:
4x Leifheit Pole/Teleskopstange (41523), expands to 4m, with is more than enough, 3m is sufficient in my opinion, I don't extend the poles all the way.
2x 8,5mm x 4,5m glas fibre rods for tents (usually consisting of 9 pieces, each 50cm), length can be adjusted
4x Heavy duty pegs (about 40cm long), like this one:
About 10m Paracord when using the heady duty pegs. (the cord should not be much thicker than 3,5mm, better 3mm, since it needs to be routed trough the glas fibre rods, which usually have a hole of about 3,8mm in my case). If you want to wind down the gravity gate (which isn't neccessary when using the heady duty pegs), you'll certainly need more. For easier routing use a lighter to "sharpen" the end of the cord.
Fabric for better visibility, e.g. from FPV cheap gate:
(1 gate is 4m long, so 2 needed for a 2x2m gravity gate)
Some M3 screws (about 10-12mm)
Printed parts from this thingi (PLA/PETG and some parts in hard TPU (D60 shore) is recommended).
This gravity gate is pretty versatile:
- You can adjust the height as desired
- You can adjust the shape by extending the pole in different ways, by changing the length of the glas fibre rods and by changing the gate shape (additional connector piece my be requiered/designed), e.g. you can also build a triangle Dive gate only needing 3 poles and less glas fibre rods/print parts.
The material cost for the 2x2m square gate is about 100€ (without filament for the printed parts, which would add about 20-30€ extra for this, depending on your filament source).
You sure can build a cheaper dive gate. This dive gate had several requierments which needed to be fullfilled and the cheaper models/variants couldn't address all of that, in my opinion:
Cost in respect to it's value
As shown in the video with some training a single person needs about 6-7 minutes for the assembly and 4 minutes for the disassembly. With more people of course even faster.
The first iteration of the dive gate used edge connectors with screws (V1) and was initially design for a triangle shape. Therefore the angle for the glas fibre rods is different. Hence of the glas fibre rods flexiblity you can also use those for a square shape. I included them as well if somebody wants to go in this direction but in my opinion the esge connectors V" are much more convenient since no tools are requiered.
Parts which should be printed in stiff TPU:
Other part with are needed (PLA/PETG/ABS):
- Gate_Edge_Rod_Connector_V2_bottom.stl (4x)
- Carbon_rod_endcap_V1-V3.stl (those are used to create a flush end for the glas fibre rods
- Peg_Holder_33_5_Spacer_mit_Lasche.stl (for reducing slack of the upper Peg Holder)
The rest is optional/not requiered and was created during the iteration process.
All parts are printed with about 50% infill, 0,2mm layer heigth and 4 perimeters.
