Self-watering Seed Starter Double-wide trays

This double-double tray rounds out the set of self-watering seed starter trays for 127mm seed starters I have modeled.  It goes with a single and double tray linked below.  It can fit any standard 127mm starter unit or the 127mm units also linked below.  They will be a tight fit, but it can fit 4 of each.  It will also fit 9 of the single largest starter pots linked below.

 

It has raised slats on the bed to allow water to flow out of the bottom of your starter pods, and optional handles to move the trays around easily.  The handles version uses threaded heat inserts and screws to attach.  You will need 4 x M3x4mm inserts for each handle, and 4 x M3x6mm screws to attach them (total of 8 each per double-wide tray).

 

This setup is part of a larger series of designs I made for your plant starting adventure.

• Small self-watering starters to begin your initial starts can be found here: Small Starter Units
• V2 Larger self-watering starters (stackable!) to transfer your small starts can be found here: Large Stacking Starter Units
• V1 Larger self-watering starters (non-stacking) to transfer your small starts can be found here: Large Starter Units
• Large single pot to finish your mature starts before moving to beds can be found here: Large Single Units
• Single and double-wide trays that fit both small and large seed starter units can be found here: Watering Trays
• Tools for seed depth setting in both Imperial and Metric units can be found here: Seed Depth Gauges
• Tools for spacing planting locations across garden beds can be found here: Seed Spacer Planting Tool
• Self-watering Lids that fit on both the small and large starters can be found here: Self-Watering Lids

This can only be printed on a larger bed, such as the X1/P1/A1.  It is also recommended to disable Flow Dynamics Calibration since the print is nearly the entire usable area of the bed.

 

 

NOTE: Make sure to re-enable Flow Dynamics Calibration on your next print since this is a persistent setting!!

 

The print profiles included are for both PETG and PLA.  I highly recommend printing in PETG, since it is much more resilient to water (PLA will biodegrade eventually).  Also PETG is much more heat-resistant if you intend to use an incubation pad, or have these in a heated greenhouse.  If you intend to have these outside, then ASA is also an option for the UV resistance.
