Everything you need to convert a standard 3oz dessert cup into a corm cup setup.
1 × Corm Cup Insert
1 × Wick String (pre-cut to size)
These inserts are designed to fit the standard 3oz dessert cups commonly used for corm cups.
I've tested them with cups from multiple suppliers, including cups advertised with top diameters ranging from 1.75" to 1.9". Despite the differing specifications, all tested cups have been identical in size and provided an excellent fit.
Tested with:
Standard 3oz dessert cups
dLux 3oz cups
Various unbranded 3oz dessert cups
If you're using a typical 3oz dessert cup, these inserts should fit without issue.
Not sure if your cups are compatible? Feel free to get in touch before ordering and I'll be happy to help.
Colours marked with ** are printed in PLA.
PLA offers the widest range of colours, best print quality and is more than suitable for the intended use of this product. While PLA is generally less resistant to prolonged heat and humidity than PETG, I have used PLA planters and self-watering outers in my grow tent that sits around 28°C and 80–95% humidity for over two years without any issue.
Colours without ** are printed in PETG.
PETG offers increased durability, better heat resistance, and improved long-term performance in demanding environments.
Both PLA and PETG are suitable for use in a corm cup, however if you prefer the most durable option with the best long-term performance then a PETG option should be chosen.
Please note: To ensure long-term durability, these inserts should be used under normal room temperature conditions. They are not designed for use with heat mats, germination mats, or other heated surfaces, as prolonged exposure to heat may cause slight warping.
