Having only 30mm handle needles I was determined to not buy another 500. Thanks to Tyler having his model available I was able to make the required adjustments to use longer handles as used in the original umikot models.
Please follow the instructions given by Tyler and redfoxdude. Needle length will be 65mm and 55mm
Thank you Tyler for your work in developing this V2 model.
UPDATE:
Re-orientated the models to printing orientation. These models should not require supports.
The author remixed this model.
