Modular spool rack on castors.

Modular spool rack for 20mm wooden dowels. It has a modular design and can be configured and extended as required. The wooden dowels are fixed with screws to make the rack even more stable.The middle section ensures that each level can be used (not shown in the pictures).Optional castor holders or fixed feet can be used. I have used the following castors:https://toom.de/p/moebel-bockrolle-mit-platte-15-mm/7367250 The following items are also required:- Drywall screws 3.9x30 (8 per unit)- 20mm wooden dowels (4 per unit)- PLA glue- (Optional) For the castors M4x10 screw (8 per unit) The design was inspired by:https://www.thingiverse.com/thing:5865345But I created it completely new in CAD with all adjustments.
