This drawer version for the iSpindel Project is made ecpecially to fit petling tubes that is 33x123mm. I bought them here: https://www.ebay.com/itm/5-XL-BIG-PET-Micro-Geocaching-container-geocache-Petling-preform-soda-bottle/132379354446?hash=item1ed26ca54e:g:0LkAAOSwe-FU4GqL:rk:1:pf:0 Kudos to Frankdaastoel and his description (in Norwegian) https://daastoel.com/2017/02/25/ispindle/ This petling tube fits nicely in the holder that he has designed here:https://www.thingiverse.com/thing:2169567 He also has a Wireless edition that fits this tube, I did however make a new drawer so i could build the electronics exactly as described on GitHub without any modifications (exept for the Wireless charging): https://github.com/universam1/iSpindel/blob/master/docs/README_en.md build instructions here: https://github.com/universam1/iSpindel/blob/master/docs/iSpindelbreadboard_en.md Note that the battery bay is a few mm longer than the NCR18650b battery i used, reason is to be able to fine tune the weight distribution by moving the battery. I was able to get very close to 25 degrees tilt without any additional weights. I aim for 25 degrees tilt in water. This is a good starting point for calibration. I used some hot-glue to fix the battery when i was happy with the tilt Kudos to everyone that has contributed to this fantastic DIY project, perfect for home brewers. I have integrated the iSpindel with Craftbeerpi 3.0 Works great.
